TiO2-ZrO2 mixed-oxide membranes were prepared via polymeric sol-gel technique. The final composition is already predefined during the preparation of the sols by using the corresponding quantities of the starting alkoxides. The mixed-oxide membranes were characterized by Xray diffraction, nitrogen sorption, and field emission scanning electron microscopy as well as filtration and corrosion tests. The observed results prove the positive influence on the investigated properties by addition of a second oxide. Depending on the composition of the mixed-oxide membranes, a remarkable increase in the crystallization temperatures is demonstrated. Using mixed-oxide systems, the retardation of grain growth is confirmed.

Fluorescence Peak

Quantum size ZnO colloids were prepared by sol-gel method and size of colloids together with the luminescence properties were changed by varying preparing time and temperature. The absorption onset and the maximum of fluorescence peak of the ZnO colloid have obvious shift in UV region and visible light region respectively. The relationship between luminescence properties and energy level splitting is discussed in detail based on the experimental results.

Zinc oxide nanoparticles (ZnO) exhibit numerous characteristics such as biocompatibility, UV protection, antibacterial activity, high thermal conductivity, binding energy, and high refractive index that make them ideal candidates to be applied in a variety of products like solar cells, rubber, cosmetics, as well as medical and pharmaceutical products. Different strategies for ZnO nanoparticles’ preparation have been applied: sol-gel method, co-precipitation method, etc. The sol-gel method is an economic and efficient chemical technique for nanoparticle (NPs) generation that has the ability to adjust the structural and optical features of the NPs. Nanostructures are generated from an aqueous solution including metallic precursors, chemicals for modifying pH using either a gel or a sol as a yield. Among the various approaches, the sol-gel technique was revealed to be one of the desirable techniques for the synthesis of ZnO nanoparticles. In this review, we explain some novel investigations about the synthesis of zinc oxide nanoparticles via sol-gel technique and applications of sol-gel zinc oxide nanoparticles. Furthermore, we study recent sol-gel ZnO nanoparticles, their significant characteristics, and their applications in biomedical applications, antimicrobial packaging, drug delivery, semiconductors, biosensors, catalysts, photoelectron devices, and textiles.
