Abstract
Quantum efficiencies of Er3+-doped silicate, phosphate, tellurite and fluoride glasses have been examined under simulated sunlight excitation. The quantum efficiency of the whole emission bands was obtained as about 75 % for fluoride glass and about 2 % for silicate glass. The maximum quantum efficiency of the emission band at 1530 nm was about 35 % for fluoride glass and about 17 % for silicate glass. The product of the stimulated emission cross-section and the emission lifetime σstτf was about 46×10-24 cm2 sec for fluoride glass and about 54×10-24 cm for silicate glass. These values are about 2–4 times larger than that of Nd-doped glasses.
