摘要：

The monoclinic YNbO4: Bi3+, Sm3+ phosphors were synthesized by conventional solid state reaction method. Their luminescent properties and energy transfer from Bi3+ to Sm3+ ions were systemically investigated by excitation and emission spectra, decay curves measurement, and energy level diagram analysis. The obtained phosphors exhibit emission from Bi3+ and Sm3+ with considerable intensity under near-ultraviolet excitation due to efficient energy transfer from Bi3+ to Sm3+. Our research extends the understanding of interactions between Bi3+ and rare earth ions and provides a new platform to design and fabricate novel luminescent materials in the future.
