A family of TeO₂ based glass is one of the promissing host materials for lasers because of low phonon energy and chemical stability. Recently, it is known that LiO₂ contents influence not only glass structures but also local structure around emissive rare-earth ions doped. In this study, Eu³⁺ doped TeO₂-TiO₂-ZnO glasses were synthesized with addition of Li₂O and their photoluminescence and thermal properties were investigated.
