Photoluminescence and Physical Properties of the Nano-Zn2SiO4:Mn Phosphor Powder under the Nitrogen Atmosphere

The subject of this work was to study the photoluminescence characteristics of nanoZnO and SiO2powders into Zn2SiO4phosphor, and to achieve better control on grain size and grain shape than traditional powder. The manganese elements were used to replace Zn2SiO4defects and to achieve better control on grain size and grain shape than traditional powder. With different sintering atmosphere conditions, the effect of the photoluminescence intensity due to sintering temperature and the concentration of activator were be discussed by the X-Ray diffraction, SEM and TEM were utilized in the characterization of phase purity and microstructure of phosphor particles.
