“…Reported that, ZnO nanorods can be successfully achieved by various deposition techniques such as spray pyrolysis, chemical vapor deposition (CVD), thermal treatment, sol-gel spin coating process, immersion, etc. [10][11][12][13][14][15] that have been used to generate a structure of ZnO nanostructures. Among the aforementioned techniques, immersion technique is preferred due to its simplicity, faster operation, less power consumption, and lower cost than the other techniques.…”

The effect of precursor concentration ranging from 0.1 to 0.5 M using the mixture of zinc nitrate hexahydrate (Zn(NO3)2.6H2O) and urea (CH4N2O) at 60 oC evaluated in this study. ZnO nanostructures have been prepared by solution immersion method on gold-seeded silicon substrate (Si/Au). Solution immersion method was adopted with the intention to develop a large area deposition at low-temperature benign method of preparation. As concentration increase, the morphologies are seemingly changed from rod (~300 nm) to accumulated nanosheets that consist of many pores. The structural and optical effect of changing the precursor concentration on the synthesization of ZnO films were investigated by X-ray diffractometer (XRD) and room temperature photoluminescence (PL) measurement, respectively. A unique development of size and growth orientation is seemingly affected by the change of the precursor concentration.

Sputter deposited Al doped ZnO (AZO) thin films exhibit a dual hydrogen sensing response in the temperature range 40 °C–150 °C after surface modifications with palladium nanoparticles. The unmodified AZO films showed no response in hydrogen in the temperature range 40 °C–150 °C. The operational temperature windows on the low and high temperature sides have been estimated by isolating the semiconductor-to-metal transition temperature zone of the sensor device. The gas response pattern was modeled by considering various adsorption isotherms, which revealed the dominance of heterogeneous adsorption characteristics. The Arrhenius adsorption barrier showed dual variation with change in hydrogen gas concentration on either side of the semiconductor-to-metal transition. A detailed analysis of the hydrogen gas response pattern by considering the changes in nano palladium due to hydrogen adsorption, and semiconductor-to-metal transition of nanocrystalline Al doped ZnO layer due to temperature, along with material characterization studies by glancing incidence X-ray diffraction, atomic force microscopy, and transmission electron microscopy, are presented.
