![عکس صفحه اول مقاله: Synthesis process dependent photoluminescent properties of Zn2SiO4:Mn2+ upon VUV region Synthesis process dependent photoluminescent properties of Zn2SiO4:Mn2+ upon VUV region](/preview/png/1627182.png)
The influence of the synthesis method on VUV luminescence properties of Zn2SiO4:Mn2+ green phosphor was investigated by comparing the properties of samples prepared by four routes: solid-state reaction (SR), sol–gel processing (SG), hydrothermal process (HP) and solution combustion process (SC). On the basis of X-ray powder diffraction, SEM micrographs and photoluminescence measurements, the samples prepared through SC process have spherical-like morphology, higher luminescence intensity and shorter decay time, which is because the samples have higher crystallinity and regular, uniform spherical-like morphology. It can be concluded that SC process is the most efficient method to prepare high quality compounds for practical applications among the four methods.
