Uniform ZnO nanorods can be used to improve the response of ZnO gas sensor

Fabrication and characterization of ZnO nanofibers by electrospinning

“…The ZnO has been early and widely studied due to its high mobility of conduction electron, good chemical and physical stability, low cost, and so on [7,8]. Compared to other structural types of ZnO gas sensors, nanostructured ZnO gas sensors are reported to exhibit higher sensitivity [9][10][11][12]. From this perspective, of ZnO nanofiber based gas sensors are expected to exhibit sensing performance at very low gas concentrations.…”

Structural, diffused reflectance and photoluminescence study of cerium doped ZnO nanoparticles synthesized through simple sol–gel method

“…It is a promising material for many optoelectronic applications [4][5][6] such as ultraviolet lasers, light-emitting diodes, p-n junction devices, solar cells, chemical sensors. Due to its large binding energy (60meV), wide band gap (3.37eV) [7][8][9][10] and easy synthesis and assembly methods, the utilization of ZnO has covered various fields such as electric transistors [11], photovoltaic devices [12][13][14] and chemical and biological sensors [15][16][17][18]. Nowadays, the nanostructured ZnO materials such as ZnO nanowires [19][20][21][22][23], nanoparticles [24], and nanotetrapods [25] have attracted wide attention since their large surface area and enhanced quantum confinement lead to novel electrical and optical properties for device application.…”

Investigation of ethanol vapor sensing properties of ZnO flower-like nanostructures

“…It was observed that the performance of the sample was decreased to $94%, 92%, and 92% of the maximum point of the first round at the subsequent cycles. This decrease could be explained by the fact that a small portion of the active surface of ZnO nanostructures may be blinded gradually due to humidity, temperature, and some additional external fluctuating factor, i.e., the sampling error [43].…”
