Abstract

Novel hierarchical nanostructures of metal oxides synthesized via simplistic SILAR cycles.

Modified SILAR Grown ZnO Films on p‐Si(100) with Enhanced Charge Separation for UV Light Sensing Application

“…Among the aforementioned synthesis approaches, the SILAR method for producing ZnO thin films has been recognized as one of the most appealing strategies to provide excellent fabrication conditions. [18] Owing to its simplicity, reproducibility, cost effectiveness, ability to fine-tune the particle size and form of deposited thin films, and ability to work at room temperature, SILAR seeks to make high-quality ZnO films. The SILAR approach has also been used to create hybrid structures for a variety of device applications.…”

Low-temperature operating ZnO-based NO2 sensors: a review

“…have been widely reported. [31][32][33][34][35] Although improved preparation methods and modied morphologies have signicantly enhanced gas sensing performance of ZnO-based sensors, [36][37][38][39][40][41][42] the most reported sensors still operated at high temperatures, which limited their practical applicability. Owing to ZnO-based gas sensors generally need to be heated the sensing layer to a higher temperature (300-500 C) to achieve the sensing performance, leading to a high-power consumption and changes in the nanomaterial microstructure.…”

One‐Pot Synthesis of ZnO Nanorods for LPG Sensing Applications

“…As shown, the strongest reflection observed along the (002) direction indicates that the ZnO rod arrays are preferentially well‐oriented in the direction of the c ‐axis. [ 5 ]…”

“…Thus, more test gas is adsorbed and diffused quickly on the sensor surface, leads to contribute to the enhancement of the sensing performance. [ 5 ] Among these, 1D ZnO nanostructures, such as nanorods, nanowires, nanobelts, and nanotubes have attracted a great research interest because of their scientific and technological applications. [ 6 ] ZnO is an n‐type semiconductor (e.g., 3.37 eV) with a large exciton binding energy of 60 meV at room temperature.…”
