Abstract
The physical, optical and luminescence properties of lithium aluminium phosphate glasses different doping europium oxide have been investigated to evaluate their properties for solid-state lighting applications. The density and molar volume measurements were carried out at room temperature. The absorption spectra were investigated in the UV-Vis-NIR region from 250 to 2500 nm. The emission spectra, excited with 394 nm excitation wavelength showed four emission transitions corresponding to 5D0→7F1 (591 nm), 5D0→7F2 (612 nm), 5D0→7F3 (648 nm) and 5D0→7F4 (698 nm). The optimal concentration of Eu2O3 in lithium aluminium phosphate glasses was 1.00 mol%.
