Quantum Dot-Organic Oligomer Nanostructures: Electronic Excitation Migration and Optical Memory Design

  • Artjay Javier (a1), C. Steven Yun (a1) and Geoffrey F. Strouse (a1)


Energy, in the form of an electronic excitation, can be directed within an inorganicorganic composite of semiconductor quantum dots and organic oligomers by manipulating the structural conformations of the organic component or the size of the inorganic component. Continuous-wave and time-resolved photoluminescence studies indicate that weak electromagnetic resonant coupling between discrete intra-chain and inter-chain excitations of the oligomer and quantum dot excitations can be used to produce a potentially useful optical display material. Thin film blends demonstrate a thermally-induced luminescence-detected chainmelting phenomenon that has the potential for writable optical memory.
