| Abstract: | Eu3+-doped MMoO4(M = Ca,Sr) red phosphors have been prepared by the facile Pechini method.The structures,morphologies,and properties of the obtained samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),photoluminescence emission spectra(PL) and excitation spectra(PLE),respectively.XRD results imply that we obtain target products with no impurities.SEM images show that two doping system samples perform different morphology uniformities and Eu3+-doped CaMoO4 samples have smal... |
