摘      要：This paper reports the comparative investigations of the structural and spectral properties of Y3Al5O12∶Eu3+ (YAG∶Eu) and Y3Al5O12∶Eu3+,Si4+ (YAG∶Eu,Si) phosphors synthesized by combustion method at low temperature.A pure phase was identified for the YAG∶Eu phosphor with a suitable amount of *** refinement and analytical calculation of different structural parameters were performed to get the idea about the SiO2 substitution in YAG∶*** characteristic red luminescence corresponding to Eu3+ transitions was observed after irradiation with ultra violet (UV) light and enhanced with SiO2 *** formula and nephelauxetic ratio were used to understand the ligand behavior of Eu-O bond in YAG doped *** Judd-Ofelt intensity parameters and color properties of the phosphors were determined in *** efficient synthesis method for YAG∶Eu phosphor,compatible for industrial applications,was proposed.
