Paper Title:
Tb3+ Doped CaMgSi2O6-Based Green Phosphor
  Abstract

SiO2,CaO and MgO was chosen as main raw material and Solid State method was used to prepare the sample. The precursor was directly sintered at 1000°C with reducing atmosphere for 3 h to obtain new green CaMgSi2O6:Tb3+,Li+Phosphors.The effects of the content of the doping ions Tb3+ on the luminescent properties have been studied. The structure, morphology and luminescent properties of the phosphors were characterized by XRD,SEM,UV and PL-PLE spectra respectively.The results showed that the CaMgSi2O6:Tb3+,Li+ was base-centered monoclinic crystals, the phosphor particle distributed uniformly.The phosphor has a strong absorptive capacity excited by 230 nm ultraviolet ray, and could emit the strong green light with the wavelength of 543 nm(5D4→7F5). The CaMgSi2O6:Tb3+,Li+ is a new type of green fluorescent material.
