摘要：
Rare earth (Dy3+, Sm3+) ions doped and undoped NaMgSO4F polycrystalline phosphors were synthesized by simple route of re-crystallization method. The crystalstructure of doped and undoped material was characterized using X-ray diffraction (XRD). Optical absorption and emission analysis and decay curves were carried out to find efficient energy transfer within co-doped phosphors. The multicolor emission from co-doped materials at characteristic excitation suggests a well defined approach towards energy transfer emission for white light emission (W-LEDs).
