Abstract

doped SnNb

powders were synthesized by molten-salt growth method. The structure and morphology of SnNb

:Sm

were characterized by X-ray diffractometer and scanning electron microscope. The photoluminescent properties were studied by the excitation

emission spectra and fluorescence lifetimes. The results reveal that the obtain samples are monoclinic SnNb

powders. Under 407 nm excitation

strong red-orange luminescence can be observed

and the strongest emission peak is located at 599 nm

corresponding to
