Abstract

The invention relates to a fluorescent material. The fluorescent material comprises the following components in parts by weight: 40-55 parts of N-R substituent-p-nitroaniline, 4-8 parts of zinc silicate, 5-10 parts of zinc cadmium sulfide, 8-15 parts of fluorescent yellow, 2-5 parts of morin, 10-15 parts of a cyclic phenolic compound, 3-9 parts of zirconium oxide, 2-7 parts of aluminum oxide, 4-10parts of garnet and 5-10 parts of mesoporous acrylamide polymer nanoparticles. Compared with the prior art, the fluorescent material has the beneficial effects: through the improvement on a formula of a fluorescent material disclosed by CN103074063A, the proportions of the N-R substituent-p-nitroaniline and the fluorescence yellow are appropriately increased, the proportions of other components are adjusted, and then a fluorescent polymer with fluorescence intensity, namely the mesoporous acrylamide polymer nanoparticles, is added, so that the fluorescence intensity of the finally obtained fluorescent material is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a fluorescent material. Background technique [0002] The development carried out by Sumitomo Electric Industries, Ltd in Japan in 1999 is to form a CdZnSe thin film on a ZnSe substrate first. After electrification, the thin film emits blue light, and part of the blue light irradiates on the substrate to emit yellow light, and finally mixes to form white light. This method only uses a single LED crystal grain and does not require fluorescent substances, but the luminous efficiency and lifespan are still relatively low, which is where it needs to be further improved. Today's mainstream technology in the industry uses indium gallium nitride blue LEDs combined with yellow-emitting cerium-activated yttrium aluminum garnet phosphors (yttrium aluminum garnet, (Y, Ce) 3 Al 5 o 12 ), a white light source is formed by the complementary effect between blue light and yellow light...
