Summary
This chapter reports the optoelectronic properties of hydrothermally synthesized titanium dioxide nanorod (TiO 2 NR) with attached gold nanoparticles (AuNP) as a heterostructure on the transparent substrates. The heterostructures of TiO 2 NR are studied by changing the temperature and concentration of precursor during the experimental process. The nanostructures having nanorod morphology of TiO 2 and gold (Au) nanoparticles were characterized to study the optoelectronic properties of the samples. The electronic and optical properties of TiO 2 NR layer depend on the variables such as diameter of nanorod, separation among the nanorods, and porosity of the layer, which can be understood through the theoretical studies and experimental observations. The physical properties of such nanostructures have been theoretically and experimentally explored for the optoelectronic applications. Amperometric behavior during experimental photocurrent measurement due to the electron transfer from the attached AuNP (size in the range of 3–44 nm) to TiO 2 NR (diameter ~ 80 ± 5 nm) has been elucidated with theoretical electron density. Improved optoelectronic properties are observed in TiO 2 NR/AuNP heterostructure, which are found to be beneficial for device applications.
