Abstract
P-type Titanium dioxide nanorods (NRs) film has successfully prepared by growing Cr-doped TiO2 nanorods on the surface of the Fluorine doped tin oxide coated glass slide (FTO) using the hydrothermal technique. From X-ray diffraction (XRD) analysis, pure and Cr doped TiO2 were Polycrystalline with two phases, Rutile and Anatase. Optical energy gap was found about (3.0 - 3.3 eV) which is estimated from Uv-Vis and fluorescence measurements. According to hall effect measurement undpoed TiO2 NRs shows negative conductivity while doped films shows positive conductivity.
