A Novel Phenomenon of Energy Transfer in Cd_1-XZn_xSiO₃ : 0.01 Mn²⁺ Phosphor

Abstract:

Cd_1-xZn_xSiO₃:0.01 Mn²⁺ phosphor was synthesized by sol-gel method. It was characterized by excitation, emission spectra and XRD. The luminescent properties show the phenomenon of energy transfer from the tetrahedral coordinated Mn²⁺ ion to the octahedral coordinated Mn²⁺ ion after exciting by ultraviolet light, which boost the performance of the phosphor. With the increasing of Zn²⁺ in Cd_1-xZn_xSiO₃:0.01 Mn²⁺ phosphor, it was observed the excitation spectra broadened and a red shift in the emission spectra, which emission peak moved from 580nm to 589nm.
