Author Affiliations +
Novel optoelectronic systems based on ensembles of semiconductor are described. We will present here the optical and electronic properties of organic-inorganic hybrid structures that enable integration of useful organic and inorganic characteristics for novel sensing applications. Several semiconductor nanostructures with both direct band gap and indirect band gap will be discussed in a few different polymer and biological matrices. A number of these colloidal semiconductor quantum dots and related quantum-wire structures have been characterized using absorption, photoluminescence, and Raman measurements; these Raman measurements include those made on self-assembled monolayers of DNA molecules terminated on one end with a common substrate and on the other end with TiO2 quantum dots. The electronic properties of these structures are modeled and compared with experiment. Devices fabricated with these materials as well as their potential for sensing will be discussed.
