Abstract

Luminescence characteristics of Er³⁺-doped Li₂O-Al₂O₃-SiO₂ (LAS) glass and glass-ceramic were evaluated by measuring their absorption spectra, fluorescence spectra and fluorescence lifetime. The absorption cross section of ⁴I_13/2 - ⁴I_15/2 transition at 1.5 μm increased after cerammization. In contrast, fluorescence intensity of the 1.5 μm emission, fluorescence lifetime, τ_f and the Quantum efficiency, η calculated from τ_f and spontaneous emission probabilities decreased after cerammization. The decrease of τ_f and η was attributed to the increase of the nonradiative decay rate, W_nr caused by accumulation of Er³⁺ ions in the glass matrix containing OH ions by cerammization.
