Ceramic fluorescent luminescent material as well as preparation method and application thereof
The invention relates to a ceramic fluorescent luminescent material as well as a preparation method and application thereof. The preparation method of the ceramic fluorescent light-emitting material comprises the following steps: (a) heating a nitric acid aqueous solution to a first preset temperature, and adding a rare earth oxide Tb4O7 for reaction until a colorless transparent solution is obtained; (b) carrying out acid discharge treatment, volatilizing the solution, adding deionized water for dissolving, and removing excessive nitric acid; (c) adding Al (NO3) 3.9 H2O, H3BO3 and citric acid according to a predetermined molar ratio, adding into the solution, and reacting at a predetermined temperature to obtain gel; and (d) drying and grinding the gel, and carrying out high-temperature sintering to obtain the ceramic fluorescent luminescent material. The prepared ceramic fluorescent light-emitting material can be used for preparing a fluorescent light-emitting material for a self-luminous cold light source, and the luminous efficiency of the self-luminous cold light source is improved.
