[0027] Specific examples are shown in the following table:
[0028]
[0029]
[0030] Only take Example 3 as an example to briefly describe the preparation process of the present invention, and the principles of the preparation process of other embodiments are the same.
[0031] (1) The chemical formula prepared by traditional high-temperature solid phase method is: Ba 2 ZnS 3 :aEu 2+ (a=0.05) Luminescent material.
[0032] The raw materials are barium oxide, zinc oxide, europium trioxide and sulfur. Weigh the raw materials according to the stoichiometric ratio, grind and mix them evenly, burn the raw materials in a closed crucible at 900-1200°C for 1-20 hours, and then take them out of the furnace to cool to obtain the blocky red luminescent material Ba 2 ZnS 3 :0.05Eu 2+ .
[0033] (2) The bulk red luminescent material Ba 2 ZnS 3 :aEu 2+ After being roughly crushed by a jaw crusher, it is ground into a fine powder by a ball mill, passed through a 250-mesh sie...
