文摘

With the irradiation by femtosecond (fs) laser with high repetition rate, GeS₂ micro/nano-crystalline formation and microstructural modification occurred in pseudo-binary GeS₂–In₂S₃ glass, while almost no similar change was observed in GeS₂ glass. The addition of In₂S₃ is beneficial for the precipitation of GeS₂ micro/nano-crystals. It is expected that functional micro/nano-crystals can be controllably prepared in chalcogenide glasses by fs laser irradiation through glass composition design.
