Abstract
The luminescent properties of Eu2+, Mn2+co-doped Ca2SiO3Cl2phosphors synthesized by the sol-gel method were investigated. The crystal structure, pattern and luminescence properties were characterized by the X-ray diffraction (XRD), scanning electron microscope (SEM), and photoluminescence (PL) testing. The result showed that pure Ca2SiO3Cl2was prepared at 570°C for 8h in the active carbon weak reducing atmosphere. The phosphor particles showed Eu2+by the excitation spectrum located at 365nm found that spectra with an emission peak located at a 446nm and the other emission spectrum was dominated by the green peak located at 497nm. Due to the Eu2+center transfer energy to the Mn2+center that there be an emission spectrum peak located at 580nm. Three of emission spectrum peaks stacking to white light.
