    • Femtosecond response of J aggregates adsorbed onto silver colloid surfaces 

      Yaǧlioǧlu G.; Dorsinville, R.; Özçelik, S. (2003)
      The observation of stimulated emission from J aggregates adsorbed onto silver colloid surfaces using femtosecond excitation was reported. The stimulated emission was inferred from the excitation intensity and wavelength ...
    • Hard-core Yukawa model for charge-stabilized colloids 

      Davoudi, B.; Kohandel, M.; Mohammadi, M.; Tanatar, B. (American Physical Society, 2000)
      The hypernetted chain approximation is used to study the phase diagram of a simple hardcore Yukawa model of a charge-stabilized colloids. We calculate the static structure factor, the pair distribution function, and the ...
    • Near resonant third-order optical nonlinearities of colloidal InP/ZnS quantum dots 

      Wang, Y.; Yang, X.; He, T. C.; Gao, Y.; Demir, H. V.; Sun, X. W.; Sun, H. D. (AIP Publishing, 2013)
      We have investigated the third-order optical nonlinearities of high-quality colloidal InP/ZnS core-shell quantum dots (QDs) using Z-scan technique with femtosecond pulses. The two-photon absorption cross-sections as high ...
    • Superradiant lasing from J-aggregated molecules adsorbed onto colloidal silver 

      Özçelik, S.; Özçelik, I.; Akins, D. L. (American Institute of Physics, 1998)
      The picosecond time-resolved emission spectrum of the cyanine dye 1,18-diethyl-3,38- bis-~3-sulfopropyl!-5,58,6,68-tetrachlorobenzimidazolocarbocyanine ~also known as BIC! adsorbed onto colloidal silver was examined as ...
