Synergetic Effects of ZnS Core Shell and Bisindolo Quinoxaline-Tips (BIQ-TIPs) Spreading on ZnO Nanorod-Based Light/Gas Dual Sensors.

ZnO/ZnS/bisindolo quinoxaline-tips (BIQ-TIPs) inorganic/organic nanostructures were fabricated for the application of light/gas dual sensors. Synergic effects of ZnS shell and organic BIQ-TIPs on the ZnO nanorods (NRs) enhanced the photosensing capability owing to efficient charge transfer from BIQ-TIPs to ZnO NRs. Furthermore, ZnS shells covering on the ZnO NRs further extended the photosensing spectrum of ZnO/BIQ-TIPs hybrid structures up to red light. In addition, light-assisted hydrogen gas sensing capability was boosted with the suppositional incorporation of ZnS shell and BIQ-TIPs organic materials. ZnO/ZnS/BIQ-TIPs nanocomposites are promising for light/gas dual sensing application with broadband photosensing wavelength range. [ABSTRACT FROM AUTHOR]
