摘要

Erbium doped tellurite glasses (TeO_2 + Li_2O + TiO_2) were prepared by conventional melt-quenching method to study the influence of the Er~(3+) concentration on the luminescence quantum efficiency (η) at 1.5 urn Absorption and luminescence data were used to characterize the samples, and the η parameter was measured using the well-known thermal lens spectroscopy. For low Er~(3+) concentration, the measured values are around 76%, and the concentration behavior of η shows Er-Er and Er-OH interactions, which agreed with the measured lifetime values.
