Abstract

Eu3+-doped Lu2O3 phosphor nanopowders were synthesized by co-precipitation process with NH3·H2O, NH4HCO3 and the mixed solution of NH3·H2O and NH4HCO3 as the precipitants, respectively. Effects of precipitants on microstructures and properties of obtained Lu2O3 phosphor were investigated on study of decomposition behavior of precipitate precursor by means of DTA-TG-MS and FTIR spectra. The morphologies and particle size distributions of obtained Lu2O3 phosphors were characterized. It is found that powders from the mixed precipitant method exhibits best microstructural morphology with weak agglomeration state and particle size distribution. After being calcined at 1000℃ for 2h, the average crystalline size of Lu2O3 reaches 35nm with medium particle size (D50) of 0.48μm.
