Synthesis characterization and Luminescence Properties of B2BiMg2V3O12 based phosphors with rare earth activated Dy3+ phosphor for solid state lighting

Abstract

Highly new efficient vanadate based phosphor B2BiMg2V3O12 (B= K & Na) material incapacitated through rare-earth Dysprosium (Dy) and it was characterized by high temperature solid-state synthesis. Equipped phosphor was established by X-ray diffraction method. In Photo-luminescence measurements shows that the prepared phosphors doped by Dy is excited by near UV ultraviolet light reaching after 300 nm to 380 nm efficiently acceptable to recognize the emission in visible spectrum (in the range 400 nm –570 nm. The highly efficient prepared phosphor doped with lanthanide doped with Dy phosphor likewise showed the exact emission point at 487 nm and 571 nm at the excitation point at 325 nm. Hence, these prepared phosphors can find numerous applications as green emitting phosphor in the field of solid-state lighting area.
