Preparation and luminescence properties of SrWO4 phosphors with Ce3+ doping

Abstract

Efficient UV excitable Ce3+ ion activated SrWO4 phosphors, which were successfully prepared through a hydrothermal method. X-ray diffraction, field-emission scanning electron microscopy, CIE color coordinates and photoluminescence were used to characterize the samples. The effect of adding pH solution on the luminescent properties of SrWO4: Ce3+ was studied, the luminescence material SrWO4:Ce3+ exhibits intense blue photoluminescence (PL) with the maximum peak located at 306 nm, which is ascribed to the 4f→5d transition of Ce3+, All these results indicate that the SrWO4: Ce3+ phosphor holds tremendous potential for practical applications in and display with high performance LEDs.
