Abstract

The near-infrared emission of low phonon (805 cm^-1) germanate glasses from GeO₂-Ga₂O₃-BaO system co-doped with 0.7Yb₂O₃/(0.07-0.7)Ho₂O₃ ions has been investigated. Luminescence at 2.1 μm corresponding to ⁵I₇ → ⁵I₈ transition in holmium was obtained by energy transfer between Yb3+ and Ho3+ ions. The optimization of the activator content and the concentration ratio were conducted with the purpose of maximizing the efficiency of energy transfer and as a consequence luminescence intensity at 2mm. The highest value of the luminescence intensity was obtained in glass codoped with 0.7Yb₂O₃/0.15 Ho₂O₃.
