In this paper, the Dy3+-doped borosilicate glasses are fabricated by high-temperature melting method. The excitation and emission spectra of the glasses are measured to discuss their spectroscopic properties. The effects of the glass composition and the Dy3+ doping concentration on the emission spectrum and the luminescence intensity of the sample are investigated. We also calculate their color coordinates, which are all in the white region. By adjusting the intensity ratio of the yellow band to the blue band, which varies with the composition of the glass host and the doped concentration of Dy3+ ions, we implemente the effective white light on a single host under the excitation of 387 nm long-wavelength UV.
