Embodiment 1
[0033] This embodiment provides a magnesium-erbium-ytterbium-tridoped sodium niobate, which is prepared by the following preparation method.
[0034] 1. Weigh 0.2712mmol of ytterbium nitrate pentahydrate, 0.0904mmol of erbium nitrate pentahydrate and 0.01mol of magnesium chloride hexahydrate and dissolve them in 40ml of deionized water in sequence.
[0035] 2. Weigh 0.15mol sodium hydroxide and dissolve it in the mixed solution in step 1, add 40mL ethylene glycol and mix well.
[0036] 3. Slowly add 0.0049 mol of niobium pentoxide to the mixed solution in step 2, stir evenly, then move to the reaction kettle at 270°C for 24 hours.
[0037] 4. After the reaction, the mixed solution in the reactor was filtered, and the obtained solid powder was dried at 80° C. for 8 hours.
[0038] 5. Finally, the powder sample was calcined at 1050° C. for 2 hours.
