【 摘 要 】

ZnS nanoparticles co-doped with Sm3+ions were prepared in methanol medium for fixed Sm3+and varying ZnS concentrations. Enhancements in absorption as well as photoluminescence efficiency of the co-doped samples were observed. This enhanced efficiency is attributed to the effective increase in oscillator strengths of the Sm3+transitions because of the addition of ZnS nanoparticles.
