Solution processed multi-layered thin films of Ge₂₀Sb₅S₇₅ and Ge₂₀Sb₅Se₇₅ chalcogenide glasses.

ABSTRACT: Solution processed non-toxic Ge₂₀Sb₅Se₇₅ chalcogenide glass thin films were deposited using spin-coating method from n-propylamine-methanol solvent mixture in specular optical quality. Optical properties, composition, structure, and chemical resistance were studied in dependence on the annealing temperature. Significant increase of refractive index and chemical resistance caused by thermoinduced structural polymerization and release of organic residua were observed. The high chemical resistance of hard-baked thin films allowed repeated direct depositions by spin-coating, increasing total thickness. Multilayered thin films of amorphous Ge₂₀Sb₅Se₇₅ and Ge₂₀Sb₅S₇₅ were also successfully prepared
