    Electric field effects on optical properties of semiconductor nanorods
    (2009-05) Gurinovich L. I.; Lutich, A. A.; Stupak, A. P.; Prislopskii, S. Va.; Artemyev, M. V.; Rusakov, E. K.; Demir, Hilmi Volkan
    We studied electric field effects on optical properties of CdSe/ZnS nanorods integrated in thin films sandwiched between transparent electrodes. It was demonstrated that P-polarized component of the photoluminescence of CdSelZnS nanorods is quenched stronger by external electric field than the S-polarized component. Quantum dots are more sensitive to external electric field than the nanorods. A mechanism of external electric field influence on the luminescence spectrum of semiconductor nanorods is discussed.

    Luminescence in quantum-confined cadmium selenide nanocrystals and nanorods in external electric fields
    (Pleiades Publishing, 2009) Gurinovich, L. I.; Lutich, A. A.; Stupak, A. P.; Prislopsky, S. Y.; Rusakov, E. K.; Artemyev, M. V.; Gaponenko, S. V.; Demir, Hilmi Volkan
    It is found that the absorption and luminescence spectra of CdSe nanocrystals and nanorods depend on the external electric field. It is shown that the external electric field quenches the P-polarized photoluminescence of CdSe nanorods to a degree higher than the degree of field-induced quenching of the S-polarized photoluminescence. It is established that the nanocrystals are more sensitive to the external electric field than the nanorods. The effect of the external electric field on the luminescence properties of the semiconductor nanorods is discussed.
