Embodiment 1
[0022] Step 1: the ratio of the amount of material selected is 1:2:1.76, with 0.94mmol cesium bromide (CsBr) and 1.88mmol titanium bromide (TiBr 4 ) and 0.2ml of hydrobromic acid solution were added to a glass bottle equipped with a magnetic rotor, the glass bottle was sealed, placed on a heating magnetic stirrer, and continuously stirred at a speed of 280-400rpm for 30min to form Cs 2 TiBr 6 purple viscous solution;
[0023] Here, the preparation atmosphere is an air atmosphere with a temperature of 5-25° C. and a humidity of 20-70%. The purity of cesium bromide is 99.5%, the purity of titanium bromide is 98%, the purity of hydrobromic acid solution is analytically pure, and the mass fraction of hydrobromic acid solution is 48%.
[0024] Step 2: Open the glass bottle, suck out the purple-red viscous solution in the bottle with a pipette, add it dropwise to the evaporating dish, place the evaporating dish on the heating platform, and continue heating at 250°C for 5 minutes, ...
