Embodiment 1
[0077] After Ba (64mg), Ga (131mg), S (105mg), LiCl (110mg) and KCl (193mg) were mixed evenly, they were put into a quartz tube and evacuated to 10 -4 Seal the tube in Pa, put it into a muffle furnace and heat it to 950°C, keep it warm for 72 hours, cool down to 400°C at 5°C / h, turn off the muffle furnace and cool it down to room temperature naturally to obtain a crystal product, which is designated as sample 1.
Embodiment 2
[0079] After Ba (64mg), Ga (131mg), S (105mg), LiCl (120mg) and RbBr (180mg) were mixed evenly, they were placed in a quartz tube and evacuated to 10 -4 Seal the tube with Pa, put it into a muffle furnace and heat it to 950°C, and after 72 hours of heat preservation, turn off the muffle furnace and cool it down to room temperature naturally to obtain a crystal product, which is designated as sample 2.
Embodiment 3
[0081] After Ba (64mg), Ga (131mg), S (105mg), LiCl (130mg) and CsCl (192mg) were mixed evenly, they were put into a quartz tube and evacuated to 10 -4 Seal the tube with Pa, put it into a muffle furnace and heat it to 950°C, and after 72 hours of heat preservation, turn off the muffle furnace and cool it down to room temperature naturally to obtain a crystal product, which is designated as sample 3.
