Photoluminescence characterization of some Vanadate based phosphors

Abstract

Abstract Highly efficient new vanadate phosphor A2NaMg2V3O12 (A = Ba & Sr) doped with rare earth element Dysprosium (Dy) was synthesized at high temperature via solid-state method successfully and the formed compound was confirmed by X-ray diffraction method. Photoluminescence measurements revealed that Sr2NaMg2V3O12 phosphor doped with Dy is excited by near ultraviolet light ranging from 300 nm to 380 nm efficiently in order to realize the emission in visible spectrum (in the range 400 nm −570 nm. Ba2NaMg2V3O12: Dy phosphor also showed emission at 569 nm on excitation at 325 nm. Hence this prepared phosphor can find application as a green emitting phosphor in solid state lighting area.
