Main technical contents and invention points:

The rare earth ion co-doping technology of long afterglow material was invented: in view of the problems of low light intensity and short afterglow time of long afterglow material, different types of lanthanide rare earth ions are used for co-doping, which effectively improves the luminescence performance of afterglow material and improves the practical effect of long afterglow material.

Invented the long afterglow material nano technology: in view of the long afterglow powder and solvent compatibility problem, developed the nano technology, because the nanoparticles than the surface and excellent surface activity, effectively improved the composite effect of light and organic solvent, enhanced the adhesion of substrate and ceramics, metal, etc.

The pore making technology of long afterglow material was invented: aiming at the problems of small specific surface area and poor composite ability of long afterglow carrier material, the pore making technology of porous long afterglow material was developed. A variety of long afterglow materials were prepared by sol gel and organic slurry preparation technology. The material presents excellent porous morphology, the specific surface area is 5-8 times higher than that of the powder material, and the firing temperature is reduced by more than 200℃.

The waterproof technology of long afterglow material is developed: in view of the poor water resistance of long afterglow material of aluminate system, on the one hand, the water resistance of aluminate system long afterglow is effectively improved by spraying silicone waterproof agent on the surface. On the other hand, the organic matter was coated with calcium aluminate-based long afterglow material, which was used for photocatalytic degradation of pollutants in water, and was used repeatedly for 120 times without afterglow loss.

The preparation technology of long afterglow glass material was developed: in view of the problem that the block and powder products cannot be directly used in the field of image processing, the long afterglow material of glass in the form was invented, and the image storage function was successfully realized.
