Abstract：LaPO4:Ce,Tb nanorods were prepared by a coprecipitation method. The phase structure and morphology of LaPO4:Ce,Tb products were characterized by XRD and SEM. The excitation and emission spectra of the products were obtained by fluorescence spectrometer. The effect of Ce3+ concentration on the luminescent property of LaPO4:Cex,Tb006 nanorods was investigated. XRD patterns showed that the LaPO4:Ce,Tb phosphor is a monoclinic orthophosphate phase with a monazite structure. SEM images showed that LaPO4:Ce,Tb products were rodlike with a length of 100—1 000 nm and a width of 11—82 nm. The emission spectra showed that the strongest emission wavelength of LaPO4:Ce, Tb nanorods is 544 nm.
Key words: LaPO4:Ce,Tb; nanorod; coprecipitation method; luminescent properties
