Embodiment Construction
[0024] The matrix material is selected from analytically pure HCl, NaOH and ethanol, and the rare earth ion is selected from an oxide with a concentration of 99.99% (Y 2 o 3 、Er 2 o 3 and Ho 2 o 3 ) as the main raw material, according to the ratio of matrix materials: YCl 3 : The dopant ion is: Er 3+ , Ho 3+ . Er 3+ The volume ratio of the doping concentration is: 1% Er 3+ , Ho 3+ The volume ratio of doping concentration is: 0, 0.2, 0.5, 1.0, 1.5% ratio to measure the raw materials, the volume of each raw material solution is shown in Table 1, the YCl of 0.2mol / L 3 , ErCl 3 , HoCl 3 Drop the solution into the hydrothermal reaction kettle in proportion, then slowly add NaOH (3.5ml) solution dropwise, stir with a magnetic stirrer for half an hour, and conduct a hydrothermal reaction at 200°C for 24 hours. After the reaction, cool, add distilled water, wash with ethanol, and centrifuge The samples were dried at 100°C for 6 hours, and then annealed at 900°C for 3 hour...
