Abstract
Hybrid films of inorganic semiconductor nanoparticles dispersed in a polymer matrix combine the electroluminescent and nonlinear advantages of each component. Polymers provide a processible matrix compatible with variosu conducting and insulating substrates without latice-matching required in semiconductor epitaxy. Semiconductor nanocrystals approach atom-like densities of states, with sudden onset of excitonic transitions and concentration of oscillator strength into a narrow spectral range; tuning of spectral features through the quantum size effect; and electron/hole confinement/anticonfinement through heterostructure engineering.
