摘要: Size- (submicrometer-sized) and morphology- (spherical) controlled composite Gd–Eu oxalate particles were prepared in an emulsion liquid membrane (water-in-oil-in-water emulsion) system. The thus calcined air to obtain Gd2O3 : Eu3+ phosphor sulfur atmosphere Gd2O2S particles. These submicrometer-sized spherical showed photoluminescence properties with emission peak at 614 nm for 628 Eu3+.
