In this paper, Y2O3:Eu3+ (3%) nano powders were prepared by auto-combustion method and the effect of PH value of the precursor solution was investigated. The XRD and SEM analyses indicate that samples prepared under high PH value have less porous morphology and larger particle size, at the same time, they present stronger luminescence intensity revealed by emission. The excitation spectra show a red shift with the decrease of PH value and the decay curves show shorter lifetime with the increase of crystalline size.
Keywords:Y2O3:Eu，Combustion method，PH value
