نانوکامپوزیتcdo-zno با استفاده از روش میکروامولسیون آب در روغن سنتز شد. تأثیر سورفکتانت، نسبت وزنی اکسید روی و کادمیم و دمای کلسیناسیون بر روی مورفولوژی، تشکیل فاز، تبدیلات فازی، اندازهکریستا ل و ذرات و همچنین سطح ویژه نانو کامپوزیتcdo-zno تحقیق شد. محصولات سنتز شده توسط آنالیزهای xrd،sem ، tem،موردبررسی قرار گرفت. جهت شناسایی فازی، ویژگی های ریزساختاری و اندازه ذرات از آزمون پراش پرتوایکس (xrd...
Common II-VI compound semiconducting materials are stable thermodynamically with zincblende phase, while the II-O materials such as zinc oxide ZnO and beryllium oxide BeO are stable with wurtzite phase, and cadmium oxide CdO and magnesium oxide MgO are stable in rocksalt phase. This phase disharmony in the same material family laid a challenge for the basic physics and in practical applications...
Abstract CdO-ZnO thin films with volume ratio of (Cd: Zn) (1: 0), (0.75: 0.25), (0.5: 0.5) and (0: 1) were prepared using the sol-gel spin coating method. The as-coated annealed at 550 °C for 1 h their structural optical properties investigated. From investigations, it was observed that ZnO phase is present in composites. crystallite size values decreased increasing Zn content, dislocation dens...
CdxTeyOz/CdS/ZnO heterostructures were obtained by the SILAR method using ionic electrolytes. A CdS film was formed as a buffer layer for better adhesion of cadmium-tellurium oxides to substrate surface. In turn, ZnO previously prepared electrochemical etching form rough textured addition, an annealing mode used in oxygen stream complete oxidation process heterostructure The resulting nanocompo...
Nanobelt is a quasi-one-dimensional structurally controlled nanomaterial that has well-defined chemical composition, crystallographic structure, and surfaces (e.g., growth direction, top/bottom surface, and side surfaces). This article reviews the nanobelt family of functional oxides, including ZnO, SnO2, In2O3, Ga2O3, CdO, and PbO2 and the relevant hierarchical and complex nanorods and nanowir...
