Popis: CuI-doped GeSe2–Sb2Se3 system glass ceramics are a novel type of promising semiconductor for photoelectric application. In this study, selenide glass ceramics with different compositions were prepared by using the traditional melt-quenching method together with a 1-h annealing process at crystallization temperature. The compositional, morphological, structural and photoelectric properties of the as-prepared glass ceramics were comprehensively investigated with XRD, SEM, TEM and photo-electrochemical system. The results show that the 20 mol% CuI-doped 50GeSe2–50Sb2Se3 glass ceramics present the highest conductivity which determines the migration of photo-generated charge carriers and the highest photocurrent under visible illumination.
