摘要: Gd2O3:Eu3+ yolk–shell phosphor powders with high photoluminescence intensity were prepared by spray pyrolysis. Preparation temperature and solution concentration varied to find the optimum process conditions for preparation of structure. The formation mechanism was systematically investigated observing microstructures particles produced under various conditions. morphological structure clearly dependent on reactor precursor concentration. Eventually, pure structured obtained a reaction 1000 °C below 0.2 M. Also, formed showed thermal stability, making it possible maintain original spherical through calcination at temperatures. As result, highly crystalline having an agglomeration-free shape successfully synthesized These shown have good characteristics.
