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 Ca_0.93Bi₄Ti₄O₁₅:0.07Dy³⁺ 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.
