Abstract

The effect of SnO co-doping on Er3+ emission in the near-infrared telecommunication window has been studied in a barium-phosphate glass matrix, obtained by melt-quenching. Photoluminescence excitation spectra acquired by monitoring Er3+ 4I13/24I15/2 emission at about 1.53 μm revealed a broad UV band around 300 nm, indicating a donor/acceptor energy transfer channel. The Sn co-doped glass exhibits a five-fold enhanced Er3+ emission relative to an Er-doped reference. The absorption and photoluminescence spectra support a mechanism starting with excitation of twofold-coordinated Sn centers, followed by energy transfer to erbium ions. Pathways likely resulting in the enhanced Er3+ emission are discussed.
