Refractive indexes were measured for Ga2S3-La2S3 and Ga2S3-La2O3 samples in the range of 0.48-1.71 nm using the minimum deviation method. Data are analyzed by the Wemple equation, which is based on the single-oscillator model. These samples have relatively large average bandgaps, E0, and electronic oscillator strengths, Ed, in comparison with other chalcogenide glasses. Possible origins of these features are discussed.
