Description
In this paper, we aim to characterize the microstructure of Yttrium doped TiO$_2$ nanotubes. These were successfully synthesized by anodization method on Ti sheets. The electrolyte was composed of ethylene glycol (EG), ammonium fluoride (0.3 % wt NH$_4$F) and deionized water (2% vol H$_2$O) with different concentrations of dopant Y$_2$O$_3$. A constant DC power supply of 50 V was used during anodization with anodizing times of 2 hours. The samples were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The structural and morphological studies showed that TiO$_2$ nanotube arrays were highly ordered and the Yttrium ion dopant may be incorporated into interstitial positions of the TiO$_2$ sheets.
