Abstract
This paper studied the structural and optical properties of Dy3+-doped CaBi4Ti4O15 phosphors synthesized by a traditional solid state method. The phosphors have been characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM) and fluorescence measurements. Upon 450 nm blue light excitation, the phosphors show yellow emission centered at 574 nm with the color coordination of (x=0.44, y=0.54). And the phosphors exhibit a tunable white color emission under the near ultraviolet source by adjusting the ratio of Dy3+ appropriately. The optimal composition of Ca0.93Bi4Ti4O15:0.07Dy3+ generates white light with the color chromaticity of (x=0.31, y=0.36), indicating that CaBi4Ti4O15:Dy3+ phosphor would be a potential candidate for white light emitting diodes (LEDs) applications.
