Synthesis and Luminescence Properties of Blue Light Excited Red Phosphor SrLa2 - xZnO5:Eux (x = 0.001~0.2) for White LED
The phosphor of SrLa2 - xZnO5: Eux (x = 0.001 ~ 0.2) excited by blue light used in white LED was synthesized by high temperature solid phase.Its morphology and spectral properties were discussed.The test results by scanning electron microscopy (SEM) showed that the phosphor size regularly between 1~3 μm.The phosphor spectrum test results showed it was a broadband excitation phosphor material,the phosphor excitation spectral range of 370 ~ 520 nm and the sharp strong peak at 465nm.The shape of the emission spectrum and the location of the sample remain essentially the 625nm as the Eu3+ concentration increases.And luminous intensity reached maximum when the Eu3+ concentration was 20%.The phosphors can absorb the blue light effectively,emit the strong red light,were suitable white light LED which excited by blue light.
