Embodiment 1

[0044] Preparation of Na 5 Zr 2 f 13 :20%Yb / 2%Er nano-luminescent material

[0045] Weigh 624μL of zirconium acetate, 0.0035g of erbium acetate and 0.0423g of ytterbium acetate into a 100mL three-necked flask at room temperature, add 12mL of oleic acid and 16mL of octadecene, and stir to mix evenly. Under the protection of nitrogen flow, the above mixture was heated to 150°C and kept at this temperature for 60 minutes to completely dissolve the zirconium acetate and rare earth acetate to obtain a transparent and clear solution. After cooling to room temperature, 10 mL of methanol solution in which 0.1297 g of ammonium fluoride and 0.06 g of sodium hydroxide were dissolved was added dropwise, stirred and allowed to react at room temperature for 30 minutes. Then the mixed solution was heated to 50° C. and kept for 30 minutes to remove methanol in the reaction system. After the methanol was removed, the reaction system was heated to 290°C under the protection of nitrogen flow...
