Sol-gel derived ZnO:Y nanostructured films: Structural and optical study

First-Principles Calculations of the Electronic Structure and Optical Properties of Yttrium-Doped ZnO Monolayer with Vacancy

“…Metal doping can effectively promote the visible light harvesting ability of catalysts [14][15][16][17][18][19][20]. Yttrium (Y) is an environmentally-friendly and abundant rare earth (RE) element [21]. The radius of yttrium is close to the atomic radius of zinc (Zn), which facilitates the insertion of Y ions into the ZnO lattice [22].…”

“…So far, some studies on Y-doped ZnO have shown that impurity levels could be introduced in the forbidden band by Y doping, and the valence electron transition with low-energy excitation could improve the utilization of visible light [23][24][25][26]. The authors in [21,27] observed that the optical transmittance of Y-doped ZnO films in the visible spectral range diminishes with yttrium doping, suggesting that the absorption coefficient increases in the visible light region.…”

“…Until now, most studies on yttrium element-doped ZnO have focused on bulk, surface, and thin film forms [21,23,36]. Compared with these forms, ZnO ML of two-dimensional (2D) material has unique properties, such as larger surface areas, furnishing photocatalytic reaction sites, and a shorter transportation path for the photo-induced carriers, which are beneficial to promote photocatalytic performance [37,38].…”

A study on the effect of presence of CeO2 and benzotriazole on activation of self‐healing mechanism in ZrO2 ceramic‐based coating

“…12,13 It means that by mixing the synthesis precursors of 2 or more different metals (or metal oxides) with defined rations, we would be capable of synthesizing nanocomposite coatings in one stage using sol-gel process. [14][15][16] The chemistry of sol-gel provides a variety of methods for producing materials with desired properties, groups with organic and inorganic chemical bonds, and various materials such as ceramics, xerogels, nanopowders, and sol-gel coatings. 17,18 Among the various applications of sol-gel hybrid materials, sol-gel coatings are recognized as precursors in corrosion protection.…”
