Abstract
Light-emitting quantum dots (QDs) have been used for various optoelectronic devices and bio-sensors [1] due to tunable band gap and bright light emission. Nanoscale organic semiconductors have been utilized for heterojunction photovoltaic devices and light-emitting diodes. The hybridization of the QDs with p-type organic semiconducting nanostructures induces energy and charge transfer effects, resulting in control of efficiency of optoelectronic and photonic devices [2]. For easy hybridization, QDs can be functionalized with various chemical ligands. Depending on the hybridization types between QDs and organic semi-conductors, the energy and/or charge transfer effect can be optimized and applied to various devices. This study presents the results of multicolor optical waveguide and molecular optoelectronics using hybrids of QDs and organic semiconductors.
