Ni-doped ZnO nanowire arrays (Ni-ZnO NRs) with different Ni concentrations are grown on etched fluorine-doped tin oxide electrodes by the hydrothermal method. The Ni-ZnO NRs a nickel precursor concentration of 0-12 at. % adjusted to improve selectivity and response devices. NRs' morphology microstructure investigated scanning electron microscopy high-resolution transmission microscopy. sensitive property is measured. It found that an 8 have high for H2S large 68.9 at 250 °C compared other...
Abstract For real-application gas sensors, high performances (response, selectivity, response/recovery time and stability) are demanded. An effective strategy is applying nanomaterials in sensors. In this study, the anatase TiO 2 flower-like (FLNMs) prepared through a one-step hydrothermal method which exhibit high-performance toward acetone vapor. FLNMs sensors property characterized at optimal working temperature of 330 °C with selectivity (acetone), response ( S = 33.72 250 ppm acetone),...
Lead halide perovskites have drawn extensive attention on account of their fundamental role in the field photoelectric detection. Nevertheless, existence toxic lead ions and instability lead-based greatly hamper applications mass production commercialization. Herein, a hybrid photodetector based lead-free inorganic perovskite nanoflake (Cs3Sb2Br9 NF)/monoradicular CdSe nanobelt (NB) has been successfully prepared. The nanostructures promote effective separation electron–hole pairs, thus...
Abstract Both all‐inorganic lead‐free perovskite and CdS nanobelts possess outstanding photo‐detective properties. Herein, a hybrid photodetector based on four (NBs)/Cs 3 Sb 2 Br 9 nanoflake (NF) heterojunction fabricated by dry‐transfer tactic is designed. In this structure, parallel almost fully cover the Cs NF so that their photoelectronic advantage demonstrated. The exploited as an efficient light absorber component for construction of type‐II energy band with CdS. Compared single NB/Cs...
Both of All-inorganic lead-free perovskite and CdS nanobelts possess outstanding photo- detective properties. Herein, we designed a hybrid photodetector based on four (NBs)/Cs3Sb2Br9 nanoflake (NF) fabricated by dry-transfer tactic. In this structure, parallel almost fully covered the Cs3Sb2Br9 NF so that their photoelectronic advantage show up. The is exploited as an efficient light absorber component for construction type-II energy band with CdS. It also revealed compared single...
