The crystallization of gallium lanthanum sulfild (GLS) glasses of composition (100-x)Ga2S3.xLa2S3 (mol%) has been analyzed using X-ray diffraction, and optical and transmission electron microscopy. The major crystalline phase, X, was found to be different from the La3.33Ga6S14 phase reported previously in similar compositions. X was the primary phase present and was observed in all samples, forming on quenching as well as on subsequent heat treatment.
