چکیده

در این تحقیق نانوساختارهای اکسید تیتانیوم با مورفولوژی‌های نانوصفحه و نانولوله با دو روش متفاوت تبخیر شیمیایی و آندایز تشکیل شده‌اند و ریخت شناسی و خواص فیزیکی این دو ساختار از جمله ساختار و پاسخ نوری به‌ترتیب با دستگاه‌های میکروسکوپ الکترونی روبشی گسیل میدانی (FESEM)، دستگاه پراش اشعه ایکس (XRD) و دستگاه بازتاب پخشی (DRS) بررسی شده‌است. مشاهده شد که دو مورفولوژی متفاوت از اکسیدتیتانیوم خواص ساختاری و اپتیکی منحصر به‌فرد خود را داشته است. این خواص متفاوت فیزیکی از اکسید تیتانیوم می‌تواند منجر به کاربردهای متفاوتی از این ماده شود. بنابراین با کنترل مورفولوژی اکسیدتیتانیوم با به‌کارگیری روش‌های متفاوت امکان تغییر خواص فیزیکی و در نتیجه کاربردهای متفاوت خواهد بود.

چکیده [English]

In this paper TiO2 Nanostructures with two different morphologies of naosheet and nanotube are synthesized using chemical vapor deposition and anodize methods. Physical properties of these structures such as morphological, structural and optical are studied using field emission scanning electron microscopy (FESEM), X-ray diffractometer (XRD) and Diffusive reflection spectroscopy (DRS). It is found that TiO2 structures with two different morphologies of nanosheets and nanotubes lead to different optical responses which makes TiO2 nanostructures promissing candidate for possible applications. Therefore, morphological control is obtained using optimum experimental conditions with two different methods, which leads to achieving TiO2 nanostructures with desired physical properties.
