Abstract
A rare earth ions doped luminescent silicate glass is provided having the general formula of: 45SiO-aLiO-bMO-5AlO-3KO-2PO:cEuO, wherein a is molar ratio of LiO, b is molar ratio of MO and c is molar ratio of EuO, wherein a+b=45, 25≦a≦35 and 0.025≦c≦0.50, and wherein MO is one or more of alkaline earth metal oxides. The luminescent glass can be prepared by simple progress, without pollution and at low cost. The resulting glass can be excited by UV LED chip and blue LED chip. Bright green light can be obtained by the sample under excitation of UV LED chip, while bright white light can be obtained under excitation of blue LED chip. The luminescent glass can be coupled with LED to obtain novel LED devices and provides potential applications in the field of semiconductor lighting.
