Influence of annealing temperature on morphological, optical and UV detection properties of ZnO nanowires grown by chemical bath deposition

Property of Zinc Oxide (Zno) Nanostructures Potential for Biomedical System and Its Common Growth Mechanism

“…In addition, this synthetic strategy also does not require any certain template, surfactant membrane or epitaxial substrate to control their orientation [75,76]. Recently, various nanostructures are synthesized successfully on the basis of aqueous chemical growth method, such as nanorods [77,78], nanowires [79,80], nanoflowers [81,82], nanoneedles [83], nanoplates [84], nanosheets [85], nanotowers [24] and nanotubes [86]. The synthesis involves the hydrolysis-condensation of hydrated metal ions and complexes (inorganic polymerization) and their hetero nucleation onto substrates.…”

High responsivity and 1/f noise of an ultraviolet photodetector based on Ni doped ZnO nanoparticles

“…Until now, ZnO-based UV photodetectors with different device structures have been investigated, such as Schottky junction, p-n junction and metal-semiconductor-metal (MSM) structure. [13][14][15][16] According to the previous reports, the performance of these devices is generally dependent on the elaboration method of ZnO-based semiconductor nanomaterials. Additionally, ZnO demonstrates a large adsorption/desorption behavior of oxygen on the surface, which could decrease the dark current and increase the responsivity of the ZnO-based UV photodetectors.…”

“…Many researches using different elaboration method, demonstrate that the response speed of ZnO-based photodetectors can be improved by using dopant elements without any degradation of the responsivity. 1,[16][17][18][19] The polyol method can improve the surface properties of the oxide semiconductors, which could enhance the ability of the oxygen adsorption and desorption. 20 This method is a lowtemperature process that allows higher doping levels of dopant and leads to obtain nanoparticles with high crystalline quality.…”

ZnO Nanostructures and Electrospun ZnO–Polymeric Hybrid Nanomaterials in Biomedical, Health, and Sustainability Applications

“…In addition to the ZnO NPs, other hierarchical nanostructures acquired considerable interest in the biomedical field, thanks to their optic, optoelectronic, antibacterial, and detection sensitivity properties, as well as their selectivity with respect to particular cell lines, and the increase in cell proliferation and differentiation, which make them potential candidates for a new non-invasive approach for medical treatment [48,49,50,51]. The starting point, in order to open the way for future employment in the biomedical field of these NStr, is to understand how their morphological characteristics and physicochemical properties influence their toxicity and interaction with biological systems.…”
