摘要：

The pure Sm3+/Er3+ doped host-sensitized LaNbO4 phosphors were synthesized and characterized. By virtue of the Rietveld Method, crystal structure of LaNbO4:Sm3+/Er3+ were refined, with the occupation of dopants determined. The luminescence properties of Sm3+/Er3+ doped LaNbO4 phosphors were carefully measured and analyzed by diffuse reflectance spectra, ultraviolet and cathodoluminescence (CL). The energy transfer was recognized between host and doped Sm3+/Er3+ ions based on the luminescence spectra and decay lifetimes, which is dominated by el...
