Effect of solvent medium on the structural, morphological and optical properties of ZnO nanoparticles synthesized by the sol–gel method

Preparation of Very Thin Zinc Oxide Films by Liquid Deposition Process: Review of Key Processing Parameters

“…concentration [38][39][40], the solvent [41][42][43][44][45], the rotation speed [46][47][48][49][50][51][52][53][54][55][56][57] and the nature of the substrate [58][59][60][61][62][63]. In the present study, spin coating, which is usually devoted to the spreading of viscous solutions, is used in an uncommon configuration of fluid liquid deposition, giving rise to very thin films (<100 nm) with peculiar nano-granular morphologies.…”

“…It is known that thin films properties and morphology can be affected by postprocessing annealing temperature, which has been the subject of several works. In the case of the sol-gel spin coating technique, the morphology and properties of the film are also impacted by processing parameters such as the chelating agent [36,37], the zinc salt concentration [38][39][40], the solvent [41][42][43][44][45], the rotation speed [46][47][48][49][50][51][52][53][54][55][56][57] and the nature of the substrate [58][59][60][61][62][63].

Morphological variations in Bi2S3 nanoparticles synthesized by using a single source precursor

“…Solvents play important role during reaction process and in nanoparticles preparation; the role may include temperature control, surface passivation, regulating the particle growth and coarsening, controlling NPs shape, size, aspect ratio and size distribution [ 20 ]. The solvent, thus, provides means of achieving control over the nanoparticles, which influences the different properties of nanomaterials for specific applications [ 21 ].…”

Supercritical CO2 drying of alginate/zinc hydrogels: a green and facile route to prepare ZnO foam structures and ZnO nanoparticles

“…39 Ungula et al have synthesized ZnO nanoparticles via a sol-gel mineralization process using a sol-gel method with a systematic characterization by several analytical techniques to investigate the effect of the volume ratio of water versus ethanol on the structural, morphological and optical properties of ZnO nanoparticles. 40 Furthermore, research has shown that organizing nanoparticles into a hierarchically porous architecture with interconnected pores and a high specic surface area optimizes the functional performance and even renders new functionalities. Furthermore, several natural products have been exploited to develop nanostructured materials such as nanoparticles, 41,42 nanostructured oxides 43,44 and nanocomposites 45 by controlling their nucleation and growth.…”
