  • Anti-Stokes phosphors convert the long-wave radiation of low energy quanta into shortwave radiation rays that have a higher energy.

  • Up-conversion is a special case of a complex combination of excitation and luminescent processes in a system containing at least three energy levels.
  • the kinetics of such processes can be described by rate equations, through which the temporal change of the population density of the involved energy levels is formulated.
  • Two main up-conversion mechanisms were presented, (1) ground state absorption followed by excited state absorption (GSA/ESA) and (2) energy transfer (GSA/ETU). Beside these processes, other processes also occur in a system consisting of three energy levels as assumed for the following calculations and depicted in Fig. 2.
  • FIG. 2 is schematic drawing of possible processes occurring in a three energy level system:
  • GSA Ground state absorption
  • ESA Excited state absorption
  • ETU Energy transfer up-conversion
  • ETU Energy transfer up-conversion
  • Energy transfer up-conversion is defined as a process, whereby the ion accepting the energy is afterwards in a higher excited state than the donator before the process. If this is otherwise, the process is called cross relaxation, the inverse of energy transfer up-conversion. Less efficient are cooperative processes such as cooperative excitation (enhancing up-conversion efficiency) and the respective inverse process, cooperative relaxation (reducing up-conversion efficiency). Generally, losses caused by energy transfer, which are therefore dependent on the concentration of the dopant, are called concentration quenching.
  • the population density of the -th energy level is defined to be N, .
  • Changes in the population of the ground level No can be caused by ground state absorption, where the change in the population is proportional to the population of the level and a term, describing the probability for this transition, G 0 i .
  • the population of the ground state can be enhanced by relaxations from the higher energy levels with the Einstein coefficients as probabilities for this process. Also more complex processes, such as energy transfer up-conversion (ETU), cross relaxation (CR), cooperative excitation (CE) and cooperative relaxation (CooR), influence the population of the ground state. This kind of description can be developed for the population of each level, which leads to the rate equations for a three level system.

  • the probability of a transition within a free ion induced by incident radiation can be derived by time-dependent perturbation theory. For electric dipole transitions (when the electric field given by the incident radiation interacts with the electric dipole moment of the absorbing center) the probability can be expressed as
  • ⁇ is the angular frequency
  • ⁇ ,/ is the matrix element of the electric dipole moment
  • / is the intensity of the incident radiation
  • n is the refractive index of the absorbing medium
  • eo is the permittivity in vacuum
  • CQ is the speed of light in vacuum
  • h is Planck's constant, h, divided by 2 ⁇ .
  • the probability of a radiative energy transfer depends on the absorption cross section of the activator OA , the lifetime of the excited state of the sensitizer TS , the spatial distance R of the involved ions and the spectral overlap (given by the integral over the line shape functions g(v)). Due to the dependency on the spectral overlap the probability is high for identical ions and identical involved energy levels. When measuring the lifetime of a given transition, this effect can cause distortions to higher lifetimes, since emitted photons are trapped by other ions (photon trapping).
  • Fig. 3 illustrates energy transfer mechanisms between the ion donating energy (sensitizer) and the ion accepting energy (activator). These transfers can be radiative or non-radiative (if emission of photons is involved or not), and resonant or phonon-assisted (if the energy submitted by the sensitizer is exactly the energy received by the activator or if phonons are necessary to compensate insufficient spectral overlap).
  • ds and d A are the degeneracies of the excited state of the sensitizer and the ground state of the activator respectively.
  • the integral over the line shape functions of the emission of the sensitizer gs and the absorption of the activator g is a measure of the overlap of the involved energy levels.
  • the sum is similar to that in the Judd-Ofelt approach, where the constants 2 are analogous to the intensity parameters Q t and the reduced matrix elements describe the transitions exactly as in the Judd-Ofelt theory. With this description, resonant non-radiative energy transfer processes are described within a single mathematical form, regardless of the kind of interaction (electric dipole or magnetic dipole or higher orders).
  • Up-conversion is a non-linear effect in relation to the intensity of the incident radiation.
  • the emitted intensity I em depends on the intensity of the incident light l m via a power law, where the exponent n equals the number of required photons to excite the emitting state:
  • Fig. 4 illustrates experimental demonstration of the spectral narrowing in YF 3 :Er 3+ .
  • the dominant decay route The decay can be mainly to the next lower lying state, or to the ground state.
  • Fig, 5 illustrates input power dependence of the emission from different energy levels as a result of up-conversion processes under excitation at 1540 nm observed in CssLuaClgiEr 3"1" (1%).
  • the power dependence of the emission intensity of up-converted light on the incident intensity can be experimentally determined for a given emission by photoluminescence measurements under varying input power. Measuring external quantum efficiency of a solar cell with the up-converter applied to the rear under varying input power, the resulting signal contains the emission from all energy levels simultaneously.
  • the efficiency of a luminescent process is defined as the ratio between the desired radiative de- excitation of a certain energy level and all other possible radiative or non-radiative de- excitations. This has already been formulated for spontaneous de-excitation in the equation:
  • Table on Fig. 6 illustrates dependency of the population of an energy level Ni on the feeding power.
  • the slopes depend on the dominance of up-conversion processes compared to conventional luminescence, the dominant up-conversion (ESA or ETU) has its in the depletion mechanism, whether the relaxation more likely to the next lower level or directly to the ground state and the absorption properties of the sample.
  • the brightness of ASL is proportional to the square (or cube) of excitation intensity. Saturation is not reached even at an excitation density of 170 W/cm 2 , when the efficiency of the green emission reaches 7.3%, and that of the red one - 15%. At moderate excitation densities the energy efficiency does not exceed 1%.
  • Luminescence excitation spectra are determined mainly by the absorption of infrared radiation by the ytterbium ion, so the maximum excitation of phosphors occurs near 975 nm. This is true for all the phosphors with Yb 3+ as a sensitizer. However, the lattice of the base has a great influence on the transition probabilities in the process of emission and on the limit of conversion efficiency. In this regard, the excitation spectra differ slightly depending on the type of base of the phosphor. In Fig. 7 is shown the luminescence excitation spectra for lanthanum oxysulfide and sodium yttrium tetrafluoride; It also shows the emission spectrum of the diode of gallium arsenide doped with silicon.
  • Fig. 7 illustrates ASL excitation spectra: 1 - NaYF 4 (Yb,Er); 2 - La 2 0 2 S (Yb,Er); 3 - the emission spectrum of the GaAs— Si diode; 4 - the emission spectrum of the laser diode IDL100M-980.
  • the emission GaAs - Si can be utilized at not more than 30% in the case of fluorides, and at 60% in the case of oxysulfide.
  • Other possible sources of excitation are incandescent (especially "iodine") and high pressure xenon arc lamps, a significant portion of the radiation which is in the infrared region.
  • Incandescent lamps with an iodine cycle of approximately 3% of the total power falls on the IR radiation in the 900-1000 nm range, about as much as is found in visible spectrum radiation. Using even a portion of this energy to convert into visible radiation would increase markedly incandescent light output..
  • the complexity of solving such a problem is that the ASL absorb appreciably in the same range where they emit. Therefore, a phosphor layer coated on the lamp bulb, will greatly attenuate radiation. Furthermore, the surface of the lamp bulb is heated to 200°C, wherein the quenching of the luminescence of the majority of ASL takes place. Emission spectra

  • the characteristic emission spectra have a predominant share of the emission in the green region.
  • REM oxide and oxysulfide systems conversely, there is predominance of band intensities in the red part of the spectrum.
  • a characteristic feature of phosphors containing ytterbium and erbium is a change in emission color depending on the excitation conditions. This is due to the fact that the red bar erupted in proportion to the intensity of the excitation level of 2.5, and green - the square of the intensity of the exciting radiation. Under pulsed excitation emission the color also depends on the duration of the pulses of IR excitation. For short pulses (-100 ⁇ ) dominates the green bar, and at long ( ⁇ 500 ⁇ ) - the red one. In principle, it is possible to obtain any color using a mixture of three phosphors with blue, green and red light, and combining the excitation conditions (intensity and duration).
