Embodiment 1
[0038] 1) At room temperature, take 17mL (CH 2 Oh) 2 In a beaker, add 0.2g of KCl until a clear and transparent solution A is formed; take 17mL (CH 2 Oh) 2 In the three-necked flask, add 0.9g of Bi(NO 3 ) 3 ·5H 2 O, mechanical stirring until forming a clear and transparent solution B;
[0039] 2) Add solution A dropwise to solution B, continue to stir vigorously for 30 minutes after the dropwise addition, add Tb(NO 3 ) 3 ·6H 2 O, and Tb(NO 3 ) 3 ·6H 2 The amount of O added is Bi(NO 3 ) 3 ·5H 2 1% of the molar amount of O, placed in an ultrasonic cleaner and oscillated at 40kHz for 15min;
[0040] 3) Stop the ultrasonic vibration, transfer the obtained solution into a 40mL stainless steel Teflon-lined reaction kettle, seal it and put it in an oven at 180°C for 9 hours;
[0041] 4) The reaction kettle was naturally cooled to room temperature, the liquid in the reaction kettle was poured out, the solid precipitate was collected, washed with deionized water and etha...
Embodiment 2
[0043] 1) At room temperature, take 17mL (CH 2 Oh) 2 In a beaker, add 0.28g of KCl until a clear and transparent solution A is formed; take 17mL (CH 2 Oh) 2 In the three-necked flask, add 0.97g of Bi(NO 3 ) 3 ·5H 2 O, mechanical stirring until forming a clear and transparent solution B;
[0044] 2) Add solution A dropwise to solution B, continue to stir vigorously for 30 minutes after the dropwise addition, add Tb(NO 3 ) 3 ·6H 2 O, and Tb(NO 3 ) 3 ·6H 2 The amount of O added is Bi(NO 3 ) 3 ·5H 2 1% of the molar amount of O, placed in an ultrasonic cleaner and oscillated at 40kHz for 15min;
[0045] 3) Stop the ultrasonic vibration, transfer the obtained solution into a 40mL stainless steel Teflon-lined reaction kettle, seal it and put it in an oven at 180°C for 9 hours;
[0046] 4) The reaction kettle was naturally cooled to room temperature, the liquid in the reaction kettle was poured out, the solid precipitate was collected, washed with deionized water and et...
