| Abstract: | This paper reports physical, absorption and photoluminescence spectral properties of Eu3+-doped indium trifluoride-based optical glasses of the following formulae: 48 InF3-24 BaF2-7 AlF3-20 RF, where RF is the alkali content (LiF, NaF and KF). From fluorescence characteristics of these Eu3+-doped glasses, it is found that Glass-A with 20 M% LiF as the network modifier shows a better trend in its optical behaviour. A red emission from these glasses has been noticed upon illumination with the UV lamp. The lifetimes of the lasing transition (5D0→7F2) have been measured both at 300 and 77K with an Ar+ laser (487.9 nm) as the source of excitation. Four additional fluorescent levels at 580, 592, 598 and 653 nm have also been measured. |
