▎ 摘　　要

Graphene-structure GeSe2 nano-films (NFMs) were prepared by chemical vapour deposition. The synthesized GeSe2 NFMs were characterized by using various techniques such as SEM and XRD. Our work provides a simple and effective method to prepare GeSe2 NFMs. The GeSe2 NFM prepared by chemical vapour deposition has good uniformity and compactness, which provides a new process route for the preparation of GeSe2 NFM.
