摘要：
The luminescent properties of Eu3+ doped CaMoSiO4 red phosphor were investigated. The aim of this work is to investigate the effect of an activator on the luminescent properties of red-emitting CaMoSiO4:Eu3+ phosphor. CaMoSiO4:Eu3+ phosphors were synthesized using a combustion method to obtain small spherical particles that have smooth and round surfaces. Using urea as a fuel and ammonium nitrate as an oxidizer, CaMoSiO4:Eu3+ was successfully synthesized using this combustion method. The Eu3+ influenced the photoluminescence (PL) spectra of the produced CaMoSiO4:Eu3+ phosphors. The experiment results showed that the strongest emissions occurred with an optimal concentration of the Eu3+; it exhibited a red emission spectrum for near-ultraviolet (UV) excitation. The material would be suited for the fluorescent material used in UV light-emitting diodes (UV-LEDs). The characteristics of the synthesized CaMoSiO4:Eu3+ phosphor were investigated by means of X-ray diffraction (XRD), a scanning electron microscope (SEM), and PL detection.
