A. Use sodium tungstate (Na 2 WO 4 •2H 2 O) and Cs 2 CO 3 as raw material a. Use AR grade sodium tungstate Na 2 WO 4 •2H 2 O as raw material, configurating sodium tungstate solution for concentration of 0.5 mol/L; b. Obtain tungstic acid solution by ion exchange resin method, adding citric acid solution of concentration 1mol/L or 2 mol/L and 0.3mol/L Cs 2 CO 3 solution, stick it evenly, the precursor solution is obtained; c. Adding precursor solution into autoclave, reacting for 3days under 90℃, after ultra
B. Use WCl 6 and CsOH•H 2 O as raw material a. Weigh a certain amount of cesium hydroxide to dissolve in ethyl alcohol, weigh a certain amount of tungsten hexachloride in ethyl alcohol to obtain cesium hydroxide solution and tungsten hexachloride solution. b. Mix and stir the above obtained solution for 1h, reaction precursor solution for preparing Cs 0.33 WO 3 is obtained. c. Transfer the above precursor solution in reacting furnace, put in the dry oven for hydrothermal reaction for 1 day, the obtained pre
