preparation example Construction

[0031] In step S01, corresponding to the above-described two structures of the light-emitting substrate 13: the first one is doped with Y 3 Al x Ga 5-x o 12 : Luminescent glass of Tb luminescent material, the second is Y 3 Al x Ga 5-x o 12 : Tb luminescent thin film is formed on the substrate. The preparation method of the first light-emitting matrix 13 includes the following steps: Y 3 Al x Ga 5-x o 12 : Tb luminescent material is mixed with glass powder, then melted at a temperature of 1000-1300 ° C, cooled to room temperature, and obtained doped with Y 3 Al x Ga 5-x o 12 : Luminescent glass of Tb luminescent material, wherein the molar fraction of the glass powder composition and its components is 20Na 2O-20BaO-30B 2 o 3 -30SiO 2 . Among them, Y 3 al x Ga 5-x o 12 : Tb luminescent material is also a powder, which is mixed with glass powder in a mass ratio of 1:19 to 7:13. After mixing, Y 3 al x Ga 5-x o 12 : The Tb luminescent material accounts for...
