Abstract
ZnO quantum dots sensitized SnO2 porous nanowires were fabricated and designed for UV excitation gas sensor. The ZnO/SnO2 composite (SZQ1%) with the molar proportion of 1:100 exhibits excellent sensing properties to NO2 gas under UV irradiation at 40oC. The humidity stability of SZQ1% was also measured and discussed by DC reversed circuit and complex impedance curves. The gas sensing mechanism is well discussed and illustrated to the ZnO quantum dots sensitized and the increased photo-generated carriers under UV irradiation.
A facile synthesis approach to prepare eco-friendly white fluorescent carbon dots (CDs)/ZnO quantum dots (QDs) composites through electrostatic force was proposed, which can be used for fabrication of high-performance white...
