Example Embodiment
[0027] The present invention will be further described in detail below with reference to the drawings and specific embodiments 1-7.
[0028] The Sm-Eu-Gd three rare earth ion tantalate provided by the present invention has a general chemical formula of Sm a Eu b Gd c TaO 7 , Where a+b+c=3, and a, b, c=0.8 to 1.2. In each embodiment, the coefficients of Eu, Gd, and Sm are shown in Table 1.
[0029] The preparation steps of the above Sm-Eu-Gd three rare earth ion tantalate are as follows:
[0030] (1) Weigh Europium chloride (EuCl 3 ), Gadolinium Nitrate (Gd(NO 3 ) 3 ), samarium nitrate (Sm(NO 3 ) 3 ) And tantalum oxalate (Ta 2 (C 2 O 4 ) 5 ), added to citric acid (C 6 H 8 O 7 In ), the specific addition amount of each embodiment is shown in Table 1 (it needs to be converted into mass when weighing, and in the present invention, it is measured by mole for the convenience of expressing the stoichiometric ratio). Incubate at 135°C for 50 minutes and perform vigorous mechanical stirring ...
