Spectroscopy, thermal and optical properties of Nd3+ -doped chalcogenide glasses
Spectroscopy, thermal and optical properties of Nd3+ -doped chalcogenide glasses
We investigated the spectroscopic, thermo-optical and mechanical properties of 70% Ga2S3:30% La2S3 (mol%) chalcogenide glass and this composition doped with 0.05, and 0.2 mol% Nd2S3, prepared by melt-quenching the sulphides in a vitreous carbon crucible in a silica ampoule. The fluorescence quantum efficiency for the 0.05 mol% Nd3+ doped sample, obtained by thermal lens technique was 1.01±0.07 and the lifetime of the fluorescence of this sample was 78.00±0.05 s. The thermal diffusivity of these samples (2.7±0.1)×10-3 cm2 s-1 was determined by the thermal lens method.

Abstract
We investigated the spectroscopic, thermo-optical and mechanical properties of 70% Ga2S3:30% La2S3 (mol%) chalcogenide glass and this composition doped with 0.05, and 0.2 mol% Nd2S3, prepared by melt-quenching the sulphides in a vitreous carbon crucible in a silica ampoule. The fluorescence quantum efficiency for the 0.05 mol% Nd3+ doped sample, obtained by thermal lens technique was 1.01±0.07 and the lifetime of the fluorescence of this sample was 78.00±0.05 s. The thermal diffusivity of these samples (2.7±0.1)×10-3 cm2 s-1 was determined by the thermal lens method.
