碱性体系下水热合成ZnS∶Sm微球及其发光特性
Fabrication and optical properties of ZnS∶Sm microsphere synthesized by hydrothermal method in alkalic system
摘要
Abstract
ZnS∶Sm microsphere with spectral down-conversion function was prepared by hydrothermal method in the alkaline system using zinc nitrate and sulfur powder as zinc and sulfur sources, respectively. The influences of Sm3+doping concentration and reaction temperature on the crystal structure and luminescence property of ZnS∶Sm microsphere were discussed. XRD, PL, PLE and SEM were used to determined the morphology and property of ZnS∶Sm microsphere. The results show that the increasing of Sm3+doping concentration leads to the increasing of luminescence center and the enhancing of luminescent intensity. But when the doped concentration is up to 5%of mole fraction, concentration quenching and ZnS lattice deformation result in the decreasing of luminescent intensity. And the high reaction temperature contributes to the growth and luminescence of microsphere.关键词
