We discuss fundamental differences in electronic structure as reflected in one- and two-photon absorption spectra of semiconductor quantum dots and organic molecules by performing systematic experimental and theoretical studies of the size-dependent

We demonstrate that core/graded-shell CdSe/CdSe1-xSx/CdS giant semiconductor nanocrystals (g-NCs) have robust photoluminescence (PL) temperature response. At a size of 10.2 nm in diameter, these g-NCs undergo a PL drop of only 30% at 355 K relative t

We present two-photon absorption and excited-state absorption spectra of quantum dots of various sizes. From the linear and transient spectra we determine transition dipole moments between the states and compare them with the two-photon cross section

Nonlinear transmission upon the formation of an optically induced photonic band gap (PBG) is demonstrated by using periodic layers of optical polymers doped with highly nonlinear transition metal oxides. The refractive indices of the alternating laye

Specially-treated glass substrates coated with a thin film of water soluble mercaptopropionic acid (MPA) capped CdTe nanocrystals (NCs) were prepared and found to undergo photoluminescence changes by as much as 40% when micro-droplets of organic mole

CdTe semiconductor nanocrystals (NCs) with 3-mercaptopropionic acid as the ligand exhibit a reversible response towards inter-switching oxygen and argon environments. The photoluminescence response is investigated at multiple oxygen concentrations, N

The nonlinear optical performance of specially designed periodic structures made from composites of optical polymers and Co3O4 nanoparticles is investigated. The refractive indices of the alternating layers are designed to be close and no photonic ba

We present an agent-based iterated simulation of a simple market structure. The simulation is based on trade and price satisfaction (payoff) functions for both buyers and sellers. The participants are trying to follow the behaviour of those of their
