Abstract

A branched architecture with ZnS backbones and ZnO branches is prepared by combining a facile thermal evaporation process and a hydrothermal growth. The application of nanofilm networks made of branched ZnSZnO nanostructures as a flexible UV photodetector is demonstrated by J. Liu, X. Wang, W. Tian, and co-workers on page 3088. The fabricated devices show excellent operational characteristics: tunable spectral selectivity, widerange photoresponse, fast response speed, and excellent environmental stability.
