Abstract：In the present paper, we reported the luminescence properties of BiOCl∶Dy3+ and BiOCl∶Dy3+, Li+ phosphor synthesized by conventional solid state method. X-ray diffraction (XRD) and excitation and emission spectroscopy were used to characterize the samples. Results show that pure tetragonal BiOCl∶Dy3+ crystals can be synthesized successfully at 500 ℃, and Li+ ion dopant improves the crystallinity of samples furtherly. Under near UV light excitation, the samples give the characteristic luminescence of Dy3+ ions located at 478 (blue) and 574 nm (yellow), which show a low yellow-to-blue intensity ratio (Y/B) of Dy3+ emission and white light emission. Moreover, codoping of Li+ ion can realize the enhancement of emission intensity and the adjustment of emission color. The characteristics of BiOCl∶Dy3+ phosphor, low temperature preparation, good near ultraviolet excitation and white light emission make it to a promising near-ultraviolet WLED phosphor.
