DOIAbstract
Mesoporous titanium dioxide (TiO) nanostructured thin films, formed by a simple chemical route, namely, the successive ionic layer adsorption reaction (SILAR) technique, were efficiently used to grow a cadmium sulphide (CdS) nanoparticle architecture for device grade applications. CdS nanoparticle have a highly symmetric size and shape that could be varied in a controlled manner (<10 nm size) depending on the number of SILAR immersions without the use of an organic linker molecule. XRD and HR-TEM studies showed the formation of CdS nanoparticles on TiO nanoparticles. Such a nanomorphology showed good optical coverage over the visible region of light, and it revealed a red-shift with respect to the number of CdS layers, which was confirmed b...
