AbstractWe have investigated quantum-confined Stark effect (QCSE) on GaAs and CdSe nanocrystals and the electric field effect on surface phonons of GaAs nanocrystals isolated in sapphire substrates. For a strongly quantum-confined system, GaAs quantum dots illustrated no exciton energy shift. When the excitons are weakly confined in CdSe, a ∼ 2 meV red-shift was observed. On the other hand, the results of the electric field effect on surface phonon are dramatic both phonon oscilator strength and freqnency. As the strength of the electric field increases, the total intensity of the surface phonon decreases. At the same time, an additional peak was also observed at 277 cm-1, which is about 3 cm-1 above the center frequency of the surface phonon mode of GaAs nanocrystals embedded in a sapphire host.

In this paper, dispersion energies of Wannier–Mott, Frenkel and mixed exciton formation at the interface in nanocomposite organic–inorganic parabolic quantum dots are investigated theoretically taking account of the interaction between the two excitonic states and electric field effect. Illustration is given for three nanocomposites highly studied experimentally, such as organic P3HT combined respectively with inorganic (CdSe, ZnSe, ZnO) parabolic quantum dots. It is shown that the parameter governing the interaction between the individual exciton states depends on the inorganic quantum dot and can be controlled by the electric field. The results are consistent with the available experimental data.
