Crystal phase content-dependent functionality of dual phase SnO₂-WO₃ nanocomposite films via cosputtering crystal growth.

ABSTRACT: In this study, crystalline SnO₂-WO₃ nanocomposite thin films were grown through radio-frequency cosputtering of metallic Sn and ceramic WO₃ targets. The W content in the SnO₂ matrix was varied from 5.4 at% to 12.3 at% by changing the WO₃ sputtering power during thin-film growth. Structural analyses showed that increased WO₃ phase content in the nanocomposite films reduced the degree of crystallization of the SnO₂ matrix. Moreover, the size of the composite films' surface crystallites increased with WO₃ phase content, and the large surface crystallites were composed of numerous nanograins. Addition of WO₃ crystals to the SnO₂ matrix to form a composite film improved its light harves
