Abstract:
The first high-performance ZnO hollow-sphere nanofilm-based photodetector is constructed by 'water-oil interfacial self-assembly' of polystyrene (PS)/ZnO core/shell nanospheres and subsequent thermal treatment. The versatile growth substrate, general fabrication strategy, and high performance including excellent sensitivity, high spectral selectivity, and fast response times show the current work to be a new paradigm in the preparation of hollow-sphere nanofilm-based photodetectors.
