nanorod arrays were directly synthesized on fluorine-doped tin oxide glass substrates through a hydrothermal method. Experimental results demonstrate that a number of reaction parameters including acidity
reactant concentration
growth time and reaction temperature can affect the morphology and photocurrent density of TiO
2
nanorods. For example
the length of the nanorods significantly increases with the growth time or reaction temperature
while the diameter is only influenced by reaction temperature but not growth time. Photocurrent density firstly improves but then decreases with the reaction temperature
and there are no clear correlations between photocurrent density and growth time. These results will provide helpful information on the optimization of reaction parameters for the synthesis of oriented rutile TiO
2
nanorods with high photoelectrical conversion efficiency for solar cell applications.
