【 摘 要 】

In the present work, capped Ag NPs prepared by reduction of Ag (NO3)3by Dimethyl Formamide is doped with Sm3+in methanol and its photoluminescence behavior is studied. Significant modifications of the Sm3+ions' emission as well as quantum yield, were observed with the concentration of Ag NPs. Local field enhancement induced by neutral Ag NPs were found to be responsible for enhancement in efficiency of the Sm3+ions.
