Preparation and Characteristic Development of nano Zn2SiO4∶ Mn Green Phosphors by La2O3 Doping
In this experimental,solid state method is used to synthesize proportioned nano-ZnO and SiO2 powders into Zn2SiO4 phosphor,and to achieve better control on grain size and grain shape than traditional powder.La is used to replace Mn; and to achieve better control on grain size and grain shape than traditional powder.With different sintering conditions,With different sintering conditions,the effect of the luminescent intensity due to sintering temperature and the concentration of activator would be discussed by the X-Ray Diffraction,SEM and TEM were utilized in the characterization of phase purity and microstructure of phosphor particles.Photoluminescence (PL) spectroscopy was utilized to characterize the optical properties.This use of phosphor materials is the application of the main light source,display components.Therefore,our study zinc silicate as the main principle of doping Mn,La of the characteristics of,expects to find the best glow 1-9.
