Example Embodiment
[0024] Example 1 # :
[0025] Composition as shown in Table 1 # As shown, the specific preparation process is as follows:
[0026] According to 1 in Table 1 # The mole percentage of the glass composition, calculate the weight of each composition, weigh the raw materials and mix them evenly; put the mixture into a corundum crucible and melt it in a silicon carbide electric furnace at 1200°C for 15 minutes, and wait until the batch is completely melted Clarify for 15 minutes, pour the molten glass into a preheated mold; quickly move the glass into a muffle furnace that has been heated to 400°C, keep it for 10 hours, and then reduce to room temperature at a rate of 10°C / hour, and then cool completely Take out the glass sample.
[0027] The test results of the glass are as follows:
[0028] Take a few samples after annealing, grind them into fine powder with an agate mortar, and conduct differential thermal analysis test. The differential thermal curve of the 2.7μm infrared erbium neody...
