A series of Na3YSi2O7: Eu3+, Sm3+ samples have been synthesized via solid-state reaction technique. The phase structure and luminescence properties are characterized using powder X-ray diffraction, photoluminescence excitation and emission spectra. Effective energy transfer occurs from Sm3+ to Eu3+ and Sm3+/Eu3+ -codoped Na3YSi2O7 shows more intense red light compared to that of Eu3+-doped sample under UV light excitation.
