B2O3-SiO2-WO3-Ga2O3 glasses doped with Dy3+ were synthesized using the high-temperature melting method. The effects of different B2O3/SiO2 ratios, different Dy3+ ions doping concentrations, and alkali metal oxides on the glass structure and optical properties were investigated through the test methods of X-ray diffraction, differential scanning calorimetry, Fourier infrared spectra, and photoluminescence spectra. The oscillator strength and intensity parameters were determined using Judd-Ofelt theory, and the optical band gap for both indirect and direct allowed transitions were calculated. The glasses exhibited optimal luminous performance when the B2O3/SiO2 ratio was 50:33, Dy2O3 doping concentration was 0.5 mol%, and K2O concentration was 4 mol%, excited by a wavelength of 388 nm. The CIE coordinates falling within the white light region suggest the potential application of these glasses in white solid-state lighting.
