The kinetics of a light irradiation enhanced room temperature NO₂ gas sensor using hybrid ZnO/ZnTe nanorod structures.

ABSTRACT: This study focuses on fabricating a hybrid structure consisting of ZnO nanorods and ZnTe nanoparticles for NO₂ gas detection, particularly exploring the impact of light irradiation at room temperature (RT). The morphology, physical characteristics, and chemical properties of the ZnO/ZnTe hybrid structure are carefully studied under diverse analytical methods such as X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and other measurements. The ZnO/ZnTe composite displayed an improved response toward 500 ppb NO₂ under the blue light radiation effect. It demonstrated higher response (more than 2500%), response time (faster than 3000%), and recovery time (faster than 1000%) at RT compared with pure ZnO. Hence, blue li
