Abstract
Optical properties of Pr3+ doped lithium tellurite glass suitable for drawing fiber have been studied and profile of energy levels obtained. An excitation with 457.9 nm line of Ar+ gives strong fluorescence from 3P0,1 and 1D2 levels to various low-lying levels. It is found that the fluorescence intensity ratio from 3P1 and 3P0 levels to a common lower level viz. 3H5 at different temperatures can be used to measure the temperature.
