The investigation shows that the white light LED replaces incandescent lamps and fluorescent lamps, can effectively reduce energy consumption and reduce CO2The emission has more important practical significance at the present of global climate deterioration and energy shortage.
The use of blue LED chips (e.g., Ce: YAG yellow phosphor to produce white light) is currently the most common way to implement white LEDs. However, the exploitation and utilization of rare earth resources raises a number of environmental and economic problems. Therefore, there is a need to develop a low-cost luminescent material with high-efficiency, stable, high-quality white light emission.
Quantum dots are receiving wide attention due to their excellent properties of adjustable emission in size, high chemical stability, good optical stability, good biocompatibility, etc. Meanwhile, the luminescence property of the quantum dot is influenced not only by the size and modification thereof, but also by the assembly state thereof. Its agglomeration can red-shift the emission spectrum and increase the half-peak width. Therefore, the unmodified quantum dots can be subjected to white light by controlling the agglomeration degree of the quantum dots.
The melamine resin polymer and the polymer thereof are resin with a three-dimensional network structure, have high crosslinking density, contain triazine ring structures with higher rigidity in molecular chains, and are easy to combine with negatively charged quantum dots, so that the quantum dots can be regularly agglomerated to form microspheres. Meanwhile, the melamine formaldehyde resin has better ultraviolet-visible light permeability and thermal stability, and is beneficial to being applied to LED devices.

In some embodiments, in step S02, a melamine solution or a melamine polymer solution is prepared. For example, in some embodiments, 0.01 to 0.1 mol of amine and 2 to 3 g of paraformaldehyde are dissolved in 100ml of deionized water, stirred at 50 to 60 ℃ for 30 to 50 min, and filtered to obtain a melamine polymer solution.
In some embodiments, in step S03, the particles are prepared by heating and mixing the quantum dots and the melamine solution or the melamine polymer at a pH of 2-4 and a temperature of 80-95 ℃. For example, in some embodiments, 10 mL of a 0.01-0.1 wt% solution of melamine polymer in quantum dots is mixed with 10 mL of 25-55 mg/mL melamine polymer in solution, and stirred at room temperature for 10 min to mix well; dropwise adding 1 mol/L hydrochloric acid solution into the mixed solution, and adjusting the pH value to 2-4; then stirring for 30-50 min under the condition of heating in water bath at 80-95 ℃, and cleaning and drying to obtain the particles.
Further, in some embodiments, after the particles are separated, the particles and the second matrix are dissolved in a solvent, and then a film is deposited by a solution method, so that a thin film applied to a light emitting layer of a device can be obtained.

In some embodiments, the quantum dots are negatively charged due to the presence of the quantum dot surface ligands, while the melamine polymer and branches of the melamine polymer are positively charged. After the two are mixed, the quantum dots and the polymer are preliminarily connected together under the electrostatic action, and then under the acid catalysis and heating condition, the primary polymer is further agglomerated to form particles which are doped with the quantum dots and have a certain grid structure. When the quantum dots are agglomerated, the luminous intensity of blue light is weakened, the quantum dots which originally emit the blue light appear red light and green light, and the luminous peak intensity of red light and green light is adjusted by controlling the initial addition of the quantum dots, so that the effect of adjusting the color temperature of white light is achieved.
