The Dy3+ doped and Dy3+/Ce3+ co-doped CaO–Al2O3–SiO2–B2O3 glass for light-emitting-diodes (LED) applications had been successfully prepared by the conventional melt-quenching method. Their photoluminescence properties were characterized by excitation and emission spectra. Under UV-light excitation, the Dy3+ doped CaO–Al2O3–SiO2–B2O3 showed a yellowish white light emission. To compensate for the lack...
