Abstract

Sm3+activated Y2O2S red phosphors were prepared by the combustion method and microemulsion method at the first time Xray characterization and electron diffraction show that Y2O2SSm3+ Ti4+ Mg2+ samples prepared by these two methods are pure hexagonal crystals in structure with a trivial change due to dopants Scanning electron microscopy SEM results show that the product presents an almondlike sheet in uniform size Under the excitation of 269 nm ultraviolet light Y2O2SSm3+ samples fabricated by these two methods exhibit three main groups of red emission lines located at 564 604 and 656 nm respectively which are attributed to the transitions of 4G5/2 →6H5/2 4G5/2 →6H7/2 4G5/2 →6H9/2 respectively The samples prepared by microemulsion are seven times higher in fluorescent emission intensity and half time longer in afterglow time than that prepared by combustion
