Optical properties of chemically synthesized amorphous carbon nanotube and cadmium selenide quantum dot hybrid

With the advance of the modern technologies, the dimension of the devices are ever shrinking. Among all the materials, Silicon has become the material of choice for fabricating devices in the nanometer range due to its different favorable properties. Research is also going on the use of other type of nanostructured materials for their possible application in devices. Carbon nanotubes (CNTs) and organic and inorganic Quantum dots (QDs) are also investigated for their different favorable properties and applications. This article reports the synthesis of amorphous Carbon nanotubes-cadmium selenide quantum dots by simple chemical process. The morphology of pure and hybrid samples were studied by field emission scanning and high resolution transmission electron microscope. Detail optical properties, especially UV-Vis absorption and photoluminescence property of the as prepared hybrid samples were studied in order to judge their possible application in optoelectronic devices.
