Embodiment 1
[0019] Mole percent composition of glass: 73ZnO-10P 2 o 5 -15SiO2 2 -3.24CaO-0.1Bi 2 o 3 (the sum after adding should be equal to 100); Dissolve ethyl orthosilicate in an appropriate amount of ethanol, ammonium dihydrogen phosphate and citric acid with 2 times the molar amount of the metal ion are dissolved in distilled water respectively, zinc oxide and calcium oxide are dissolved in 1 :1 nitric acid, Bi 2 o 3 Dissolve in concentrated nitric acid, then mix the above liquids under the condition of stirring, adjust the pH=1 after stirring for 1 hour, continue stirring for 1 hour to form a sol, put it in a water bath at 80°C for sol-gel reaction for 10 hours, and form a gel , placed in an oven at 100°C for drying, then placed in an alumina crucible and treated at a constant temperature of 1400°C for 2 hours to melt the raw material into a liquid state so as to completely eliminate air bubbles, then quickly pour the melt on a stainless steel plate and use another steel plate...
Embodiment 2
[0021] Mole percent composition of glass: 65ZnO-20P 2 o 5 -10SiO 2 -4MgO-1Bi 2 o 3 Dissolve ethyl orthosilicate in an appropriate amount of ethanol, ammonium dihydrogen phosphate and citric acid with 2 times the molar weight of metal ions are dissolved in distilled water respectively, zinc oxide and calcium oxide are dissolved in nitric acid of 1:1 respectively, Bi 2 o 3 Dissolve in concentrated nitric acid, then mix the above liquids under the condition of stirring, adjust the pH=0.5 after stirring for 1 hour, continue stirring for 1 hour to form a sol, put it in a 90°C water bath for 8 hours for sol-gel reaction, and form a gel , placed in an oven at 100°C for drying, then placed in an alumina crucible and treated at a constant temperature of 1400°C for 2 hours to melt the raw material into a liquid state so as to completely eliminate air bubbles, then quickly pour the melt on a stainless steel plate and use another steel plate Flatten, anneal at 450°C for half an hour,...
Embodiment 3
[0023] (1), according to molar percentage composition: 75ZnO-10P 2 o 5 -10SiO 2 -1BaO-5Bi 2 o 3 (the sum after adding should be equal to 100), take by weighing 20g of raw materials altogether, and after the above-mentioned raw materials are ground and mixed evenly, put in the corundum crucible;
[0024] (2) Put the above-mentioned alumina crucible in a high-temperature box furnace at a constant temperature of 1500°C for 0.5 hours to melt the raw material into a liquid state so as to completely eliminate air bubbles, and then quickly pour the melt on a stainless steel plate and flattened with another steel plate, transferred to an annealing furnace and annealed at 450°C for 3 hours, then naturally cooled to room temperature with the furnace, and then taken out to obtain a bismuth-doped strontium aluminum boron glass with infrared ultra-broadband luminescence properties. Fluorescence will be generated under 800nm laser pumping, the fluorescence center is located near 1300n...
