preparation example Construction
[0033] The present invention also includes a method for preparing a fluorescent material containing aza-15-crown-5 cyclic crown ether, comprising the following steps:
[0034] Add the soluble salt of europium or terbium, L and organic solvent into the solvent heating jar, add 10~15ml of distilled water to seal, then put the sealed solvent heating jar into the muffle furnace; the soluble salt of europium or terbium, L The addition ratio of the organic solvent is 1 ~ 1.5mol: 1mol: 20 ~ 30ml; the organic solvent is xylene, cyclohexanol or DMF; the soluble salt of europium or terbium is nitrate or chloride; The structural formula of L is
[0035] , where R is H, -NO 2 ,-CHO;
[0036] First raise the temperature of the muffle furnace to 190~195°C for 48~72 hours, then lower the temperature of the muffle furnace to 50~55°C for 12~15 hours, turn off the power, and wait until the temperature of the muffle furnace drops to room temperature , the solvothermal jar was removed fr...
