The Preparation and Luminescence Properties of Stannate Red Phosphors for WLED

Abstract:

In this paper we have successfully prepared the red luminescent material of La0.01Y1.99Sn2O7: Eu3+, Dy3+ by the method of hydrothermal and sintering. The phase structure, surface morphology and fluorescence properties were investigated by the scanning electronic microscopy (SEM), X-ray diffraction (XRD), and photoluminescence (PL). The EDS showed that the luminescent material is La0.01Y1.99Sn2O7: Eu3+, Dy3+. The SEM micrographs showed uniform particles with good crystallinity of luminescent material after sintering. PL spectrum showed the increasing of Eu3+ has great benefit for the increase of the luminous intensity of luminous materials. The optimal doping amount of Eu3+ ion and Dy3+ is 1:3 (nEu: nDy).
