Embodiment 1
[0029] A. Press Eu(TTA) 2 (N-HPA) Phen formula theoretical measurement, respectively take 0.2mol.L -1 EuCl 3 Ethanol solution 10ml, add 0.2mol.L under stirring -1 1,10-Phen ethanol solution in 10ml mixed solution, then slowly drop 0.2mol.L in a water bath at 60℃ under constant stirring -1 HTTA ethanol solution 20ml and 0.2mol.L -1 N-HPA ethanol solution 10ml.
[0030] B. Adjust the pH value to 7 with triethylamine to produce a white precipitate, let the above reactant stand at room temperature for 24 hours, let it mature, filter with suction, and wash the precipitate with absolute ethanol until there is no Cl - , dried in an oven at 70°C to obtain a white solid rare earth organic complex Eu(TTA) 2 (N-HPA)Phen.
Embodiment 2
[0032] A. Press Tb 0.25 Eu 0.75 (TTA) 2 (N-HPA)Phen formula theoretical measurement, respectively take 0.75mol.L -1 EuCl 3 and 0.25mol.L -1 TbCl 3 Mix 5ml of ethanol solution evenly, add 0.25mol.L under stirring -1 10ml of 1,10-Phen ethanol solution, then heated in a 62°C water bath, and slowly dripped 0.25mol.L of -1 HTTA ethanol solution 20ml, 0.25mol.L -1 N-HPA ethanol solution 10ml.
[0033] B. Adjust the pH value to 6.5 with triethylamine to produce a white precipitate. Let the above reactant stand at room temperature for 20 h, let it mature, filter it with suction, wash the precipitate with absolute ethanol until there is no Cl - , dried in an oven at 62°C to obtain a white solid rare earth organic complex Tb 0.25 Eu 0.75 (TTA) 2 (N-HPA)Phen.
Embodiment 3
[0035] A. Press Tb 0.5 Eu 0.5 (TTA) 2 (N-HPA) Phen formula theoretical measurement, respectively take 0.5mol.L -1 EuCl 3 and 0.5mol.L -1 TbCl 3 Mix 5ml of ethanol solution evenly, add 0.25mol.L under stirring -1 10ml of 1,10-Phen ethanol solution, then heated in a 65°C water bath, and slowly dripped 0.25mol.L of -1 HTTA ethanol solution 20ml, 0.25mol.L -1 N-HPA ethanol solution 10ml.
[0036] B. Adjust the pH value to 6.6 with triethylamine to produce a white precipitate. Let the above reactant stand at room temperature for 22 hours, let it mature, filter it with suction, and wash the precipitate with absolute ethanol until there is no Cl - , dried in an oven at 65°C to obtain a white solid rare earth organic complex Tb 0.5 Eu 0.5 (TTA) 2 (N-HPA)Phen.
