[0022] Embodiment 1: Table 1 shows the glass formula and the first crystallization temperature value of Embodiment 1.
[0023] Table 1
[0024]
[0025] The specific preparation process is as follows: the first step, Cs 2 Li Y 0.99 Ce 0.01 Cl 6 Raw materials are CsCl, LiCl, YCl 3 , CeCl 3 Mix and sinter, weigh 50 grams of analytically pure raw materials according to the formula in Table 1, add 2.5 grams of NH 4 HF 2 , 2.5 g NH 4 HCl 2 , Mix the raw materials evenly and pour them into a quartz crucible to melt. The melting temperature is 1300°C and keep warm for 2 hours. Hours later, cool down to 50°C at a rate of 10°C / hour, turn off the power supply of the muffle furnace to automatically cool down to room temperature, and take out the glass; in the second step, according to the glass thermal analysis (DTA) experimental data, the first crystallization temperature of 656 ℃, heat-treat the prepared glass in a precision annealing furnace of nitrogen at 675°C for 6 hou...

[0027] Embodiment 2: Table 2 shows the glass formula and the first crystallization temperature value of Embodiment 2.
[0028] Table 2
[0029]
[0030] The specific preparation process is as follows: the first step, Cs 2 Li Y 0.9 Eu 0.1 Cl 6 Raw materials are CsCl, LiCl, YCl 3 , EuCl 3 Mix and sinter, weigh 50 grams of analytically pure raw materials according to the formula in Table 2, add 2.5 grams of NH 4 HF 2 , 2.5 g NH 4 HCl 2 , Mix the raw materials evenly and pour them into a corundum crucible for melting, the melting temperature is 1400°C, keep warm for 1 hour, pour the glass melt into a cast iron mold, then place it in a muffle furnace for annealing, and keep warm at the glass transition temperature Tg for 2 Hours later, cool down to 50°C at a rate of 10°C / hour, turn off the power supply of the muffle furnace to automatically cool down to room temperature, and take out the glass; in the second step, according to the glass thermal analysis (DTA) experiment...
Embodiment 3
[0032] Embodiment 3: Table 3 shows the glass formula and the first crystallization temperature value of Embodiment 3.
[0033] table 3
[0034]
[0035] The specific preparation process is as follows: the first step, Cs 2 Li Y 0.95 Tb 0.05 Cl 6 Raw materials are CsCl, LiCl, YCl 3 , TbCl 3 Mix and sinter, weigh 50 grams of analytically pure raw materials according to the formula in Table 3, add 2.5 grams of NH 4 HF 2 , 2.5 g NH 4 HCl 2 , Mix the raw materials evenly and pour them into a quartz crucible to melt. The melting temperature is 1450°C and keep warm for 1.5 hours. Hours later, the temperature was lowered to 50° C. at a rate of 10° C. / hour, the power of the muffle furnace was turned off and the temperature was automatically lowered to room temperature, and the glass was taken out. In the second step, according to the glass thermal analysis (DTA) experimental data, the first crystallization temperature is 678°C, and the prepared glass is placed in a nitrogen...
