[0053] After the mixture is ground and mixed, put it into a corundum crucible, place the crucible in a corundum boat, and put it into a high-temperature box-type electric furnace. Strictly control the heating rate, under the air at the temperature T (T = 1000, 1050, 1100, ...
Embodiment 3
[0056] Choose sodium nitrate, calcium carbonate, tin dioxide, germanium dioxide, and manganese carbonate as starting compound raw materials, and take four kinds of compound raw materials respectively according to the molar ratio of each element, totally 2 groups, and the proportioning ratio is as follows:
[0057] (1) Na:Ca:Sn:Ge:O:Mn=2:1:1.9995:3:12:0.0005, corresponding to x=0.05%;
[0058] (2) Na:Ca:Sn:Ge:O:Mn=2:1:1.9980:3:12:0.0020, corresponding to x=0.20%;
[0059] After the mixture is ground and mixed, put it into a corundum crucible, place the crucible in a corundum boat, and put it into a high-temperature box-type electric furnace. The heating rate is strictly controlled, and the calcining time is t=5h at the temperature T (T=1100, 1150, 1200, 1250°C) under the air. After cooling down to room temperature with the furnace, grind to obtain manganese-doped orange germanium stannate long-lasting phosphor.
