Example Embodiment
[0025] Example 1
[0026] A hydrothermal method in ZnMoO 4 The method of introducing fluoride ion in the medium comprises the following steps:
[0027] a. Weigh 432.2mg of molybdenum trioxide and dissolve it in 70ml of deionized water, then weigh 527.5mg of zinc fluoride tetrahydrate and add it to the molybdenum trioxide aqueous solution;
[0028] b. The mixed solution obtained in step a was transferred to a 100ml reactor, and hydrothermally reacted at a temperature of 150°C for 20 hours to obtain a yellow product;
[0029] c. The yellow product obtained in step b was repeatedly centrifuged and washed with deionized water and ethanol, dried under vacuum at 50°C for 10 hours, and ground into powder to obtain ZnMoO 4 :F.
