Abstract
We present our recent achievements of glasses able to produce ultra-broadband visible fluorescence. The luminescence system was Eu2+ doped low silica calcium aluminosilica (LSCAS) glass excited by blue light. The LSCAS glass has the superior properties of oxide glasses and the low phonon energy property of non-oxide glasses. The large Stokes-shift (12163 cm−1) and smoothing broadband emission (from 450 nm to 800 nm) were explained by the strong electron–phonon interaction and a remarkable nephelauxetic effect. Besides, given the broad excitation band in blue range, the commercialized blue LED will be a good excitation source. Therefore, these glasses have large potential to be used as warm-white light phosphor material.
