摘要：

One dimensional rutile-TiO2 nanoneedles (NNs) and nanorods (NRs) were grown directly on transparent conductive Fluorine-doped SnO2-coated (FTO) glass substrates using Chemical Bath Deposition (CBD) method. Titanium (III) chloride was used as the precursor, followed by annealing at 200 degrees C. The heat treatment leads to the conversion of TiO2 nanoneedles into nanorods. Optical studies revealed that rutile-TiO2 thin films have a high absorption coefficient and a direct bandgap which decreased slightly (3.14-3.09 eV) by applying heat treatment. The ease of deposition of rutile-TiO2 nanocomposite with different morphologies at low temperature provides a new insight for potential applications in solar cells, sensors, catalysis and separation technology.
