Abstract: Optical properties of different halide modified germanium gallium sulfide glasses doped with Nd3+ ions are presented. Glasses studied were of the compositions: 50GeS(2)-25Ga(2)S(3)-25CsX, doped with 0.5 at.% Nd3+ where X is Cl, Br or I. Absorption spectra were measured and oscillator strengths calculated. Excited-state emission lifetimes were calculated by the Judd-Ofelt theory and compared with the measured lifetimes. Results were compared with a pure sulfide glass of the composition: Ge25Ga5S70. The halide modified glasses have been found to present a unexpected reversible water sensitivity.
