Embodiment 1
[0045]According to the formula in Table 1, calculate the weight of the corresponding components, weigh the raw materials and mix them uniformly; put the mixture into a platinum crucible and melt it in a silicon carbide rod electric furnace at 900°C for 20 minutes to obtain molten glass. During the glass melting process, high-purity oxygen is always passed through for atmosphere protection to remove moisture in the molten glass. After the dehydrated glass liquid is homogenized and clarified, it is quickly poured into a mold that has been preheated to 360°C, and then quickly placed in a muffle furnace that has been heated to 410°C and kept for 2 hours; The muffle furnace is lowered to 100° C., then the muffle furnace is closed, and the temperature is lowered to room temperature to obtain the annealed erbium and terbium co-doped fluorohalophosphate glass.
[0046] The annealed erbium and terbium co-doped fluorohalophosphate glass was processed into a 10×20×1 mm glass plate and po...
Embodiment 2
[0049] According to the formula in Table 1, calculate the weight of the corresponding components, weigh the raw materials and mix them evenly; put the mixture into a platinum crucible and melt it in a silicon carbide rod electric furnace at 950°C for 15 minutes to obtain molten glass. During the glass melting process, high-purity oxygen is always passed through for atmosphere protection to remove moisture in the molten glass. After being homogenized and clarified, the water-removed glass liquid is quickly poured into a mold that has been preheated to 370°C, and then quickly placed in a muffle furnace that has been heated to 420°C. The rate is lowered to 100° C., then the muffle furnace is closed, and the temperature is lowered to room temperature to obtain the annealed erbium and terbium co-doped fluorohalophosphate glass.
[0050] Take the erbium and terbium co-doped fluorohalophosphate glass after the above annealing, grind it into a fine powder with an agate mortar, and con...
Embodiment 3
[0056] According to the formula in Table 1, calculate the weight of the corresponding components, weigh the raw materials and mix them uniformly; put the mixture into a platinum crucible and melt it in a silicon carbide rod electric furnace at 1000°C for 18 minutes to obtain molten glass. During the glass melting process, high-purity oxygen is always passed through for atmosphere protection to remove moisture in the molten glass. After the dehydrated glass liquid is homogenized and clarified, it is quickly poured into a mold that has been preheated to 370°C, and then quickly placed in a muffle furnace that has been heated to 425°C, and kept for 3 hours, and then heated at a temperature of 9°C / hour. The rate was lowered to 110° C., then the muffle furnace was closed, and the temperature was lowered to room temperature to obtain the annealed erbium and terbium co-doped fluorohalophosphate glass.
[0057] The annealed erbium and terbium co-doped fluorohalophosphate glass was proc...
