Semiconductor and metallic nanomaterials and nanocomposites possess interesting linear absorption, photoluminescence emission, and nonlinear optical properties. Nanomaterials having small particle sizes exhibit enhanced optical emission as well as nonlinear optical properties due to the quantum confinement effect. Synthesis, characterization, and measurement of optical properties of nanomaterials with different anisotropic shapes have also drawn significant attentions. Recently, a lot of research focuses have been given on the preparation of polymer semiconductor and other nanocomposites materials having potential applications in different optoelectronics and photonics devices. The synthesis of reduced graphene oxide (RGO) or graphene oxide-semiconductor nanocomposite with well-dispersed particles has gained a lot of attention due to its astonishing optoelectronic properties.
