| Abstract: | Sm3+ doped SnNb2O6 powders were synthesized by molten-salt growth method. The structure and morphology of SnNb2O6 :Sm3+ 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 SnNb2O6 powders. Under 407 nm excitation, strong red-orange luminescence can be observed, and the strongest emission peak is located at 599 nm, corresponding to 4G5/2→6H7/2 transition of Sm3+. |
