ZnO 3D flower-like nanostructure synthesized on GaN epitaxial layer by simple route hydrothermal process

Effect of reaction temperature on surface morphology and photoelectric properties of ZnO grown by hydrothermal method in mixed solvent

“…The UV emission peak at about 378 nm is corresponding to the ZnO thin film. The result is good consistent with the reports of other researchers [15,16]. Generally, the UV emission is attributed to the radiative recombination of free excitons.…”

“…Generally, the UV emission is attributed to the radiative recombination of free excitons. Effect of reaction temperature on position of UV emission peak may be attributed to quantum confinement and nanoparticle shape of ZnO thin films [15]. It has been generally accepted that the green emission in the range between 440 and 650 nm is associated with oxygen vacancies [17,18].…”

Formation, transformation and superhydrophobicity of compound surfactant-assisted aligned ZnO nanoplatelets

“…Among these methods, a simple and effective method such as hydrothermal method involving not complicated equipments of reactions is especially suitable for the easy and economic platform in ZnO nanostructure synthesis. 15 In addition, we noticed that in hydrothermal method, how to control the supersaturation of reactants is very important to obtain the expected nanostructures. Although the quantitative information is not easily available to completely understand the role of supersaturation in nucleation and growth process, it is generally found that the high supersaturation is of advantage to the initial nucleation while the low supersaturation favors the crystal growth.…”

Characterization of Nanocrystalline ZnO Flakes Synthesized by a Simple Reaction Process

“…It is reported that sensors based on ZnO nanoflake structures have an improved performance and a higher sensitivity compared to ZnO nanorods/nanowires 15) . To synthesize uniform nanosized ZnO particles and control their sizes and morphology, a variety of techniques have been used such as thermal oxidation of metallic zinc, hydrothermal methods, plasma chemical synthesis, laser ablation and vapor condensation [16][17][18] . Among these various fabrication techniques, the wet chemical route promises to be simpler, less energy intensive, less expensive -which is more profitable for large-scale production 19) .…”
