Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.Advantages of the present invention and effect will pass through content disclosed in this invention
It is and more notable.Illustrate that appended attached drawing simplified and used as illustrating herein.Attached component count shown in figure, shape and ruler
It is very little to modify according to actual conditions, and the configuration of component is likely more complexity.Also other aspects can be carried out in the present invention
Practice or application, and without departing from spirit and scope defined in the present invention under conditions of, various change and adjustment can be carried out.
According to existing Nano diamond magnetic field sensing technology, need to be introduced into microwave to operate the electron spin in NV, so
And the introducing of this condition, lead to not realize complete optical magnetic field sensing technology.
The basic conception of the present invention is, utilizes nano fluorescent structure --- the NV colour centers in diamond realize full optics magnetic
Field sensing and method, using full optical magnetic field measuring technique, eliminate some device architecture complexities, can be external to avoid introducing
Microwave radiation and relevant microwave device.
One side according to embodiments of the present invention provides a kind of diamond nano full optical magnetic field sensors, including：
Diamond nano structure containing nitrogen-vacancy colour center is configured to change fluorescence lifetime and light under different magnetic field
Photoluminescence intensity；
Luminescence generated by light detects device and/or fluorescence lifetime detection device, and the luminescence generated by light detection device is configured to detect
The fluorescence lifetime, fluorescence lifetime detection device are configured to detect the photoluminescence intensity.
In some embodiments, the luminescence generated by light detection device includes avalanche diode, single photon counter and high speed
Data Acquisition Card.
In some embodiments, the fluorescence lifetime detection device packet includes avalanche diode, single photon counter, pulse
Signal generator and high-speed figure capture card.
The material that the embodiment of the present invention can be applied to has：Diamond nano structural material containing NV (receive by nano particle
Rice noodles etc.) and diamond single crystal containing NV or polycrystalline bulk material and they various tied substantially containing diamond NV colour centers
The derivative of structure or micro-nano technology structure.
The embodiment of the present invention utilizes following principle：
I) nitrogen negatively charged in diamond-vacancy colour center (NV) defect be by with the sky in diamond adjacent cells position
The associated nitrogen-atoms (N) that substitutes in position (V) forms, and has C3v symmetrical structures, symmetry axis is in nitrogen-atoms --- on the line of vacancy,
Its Vacancy captures electronics.Under outer magnetic field condition, the photoinduction spin polarization of this NV defects and spin correlation luminescence generated by light
(PL) it can become inefficient, the information in the magnetic field about this can be extracted using NV defects optic response.Again because of NV colour centers
Lattice structure minimum dimension~0.5nm, it is possible to for nanosensor field.
By taking single NV as an example, such as Fig. 1, using the millisecond pulse light of 532m by NV colour centers, spin polarization in bulk diamond
To the excitation state of ms=0, then apply the pulse of microwave half period；Excitation state is made to be turned to ms=± 1 by ms=0, then again into
Row fluorescence lifetime measurement.The service life of excitation state ms=0 repeatedly measured is 12.0ns, and the service life of excitation state ms=± 1 is
7.8ns, aging variation is mainly since ms=± 1 is caused by metastable nonradiative transition process.
As shown in Figure 2 A and 2 B, NV models are thought of as seven level systems.Because of each energy level (comprising splitting energy level and
Intermediate state energy level) the life time of the level and fluorescent emission intensity difference.It is constant in conditions such as external laser, only change the feelings in magnetic field
Under condition, external magnetic field can cause NV electron energy level cloth inning to change (laser reduces the polarization of NV electron spins),
The relaxation time of its fine-structure levels changes, and fluorescence lifetime is caused to reduce, and photoluminescence intensity increases with magnetic field and reduced.
Ii) interpretation of quantum mechanics of above-mentioned reason is as follows：
Consider that there are NV during outfield-Ground state Hamiltonian is written as：
It can see NV-Energy level it is affected by magnetic fields larger, without influence of the equidirectional magnetic field to energy level also not
Equally.Under normal conditions in diamond stress influence very little, here we ignored.Consider that spin for 1 system, solves Xue
Determine straightforward words equationIt obtains：
It willβ is abbreviated as, and is enabledEnergy eigenvalues equation is then obtained (after for simplicity,
Face will use natural unit system, i.e.,)：
Solution formula (1.3) can obtain ground state level distribution.But generally for simplicity, perturbation approximation may be used to locate in we
Reason.Because null field splitting D corresponds to magnetic field of the 1000 Gauss sizes along the symmetrical axis directions of NV, thus can be by the magnetic field of tens Gausses
It influences to consider into perturbation (geμB|B|D).In this way：
Matrix form be：
Zero level intrinsic energy is：
The single order of energy is modified toSecond order is modified toTherefore it adds in
Behind magnetic field, the correction term of energy is：
It can be seen that, in low-intensity magnetic field, vertical direction magnetic field is to the contribution of energy shift than axis from formula (1.9)
Contribution to magnetic field is small.There are external magnetic field in an axial direction, two energy level m of script degeneracys=± 1 produces and splits
It splits.Simultaneously because perpendicular to axial magnetic field, ms=± 1 and msEnergy level spacing between=0 is widened.
The Hamiltonian variation of NV ground state levels (Spin-triplet) caused by the symmetrical axis direction magnetic fields of NV only has diagonal item,
The eigenstate of spin will not be changed；And there is nondiagonal term in the magnetic field Hamiltonian of symmetrical axis direction.Work as vertical direction
When magnetic field is very strong, the eigenstate of system is no longer spin ms=0, ± 1, but their superposition state.Laser is to spin in this way
Polarization will reduce.
So NV colour center cloth inning change overall trend is caused by the enhancing of external magnetic field：Service life is smaller and luminescence generated by light
The small corresponding energy level of intensity cloth inning distribution increase, as a result be exactly experiment measure the single NV colour centers service life with magnetic field increase and
Reduce, photoluminescence intensity increases with magnetic field and reduced, as shown in figs. 7 a and 7b.
According to above analysis, the physical principle of the embodiment of the present invention and conclusion of the present invention are as shown in figure 3, when external magnetic field (B)
In the range of 0-150G, single NV luminescence generated by lights (PL) STATISTICAL STRENGTH value in diamond nano structure with magnetic field (B) increasing
Reduce greatly, and contrast declines generally more than 30%；Its fluorescence lifetime statistical value also reduces with the increase in magnetic field.It can
Know, the service life that NV is partly described on Fig. 3 increases with magnetic field and reduced, and Fig. 3 lower parts have demonstrated photoluminescence intensity with magnetic field
Increase and reduce.
The embodiment of the present invention also provides a kind of diamond nano probe containing single NV, is used as full optical magnetic field and visits
Survey sensor.A kind of micro-nano technology process schematic representation such as Fig. 4 of typical diamond nano probe array, step are as follows：
First, spin coating HSQ is 300nm again after deposition 300nm thickness SiNx on the diamond (referring to subgraph (a))；
