Sharp and intense excitonic photoluminescence is observed at low temperatures in highly uniform pentacene monolayers deposited on a compliant polymeric substrate. The free exciton (FE) emission displays characteristic intensity that grows quadratically with the number of monolayers N. The energy of the FE band redshifts with increasing N revealing impact of molecular overlap on the FE state.

    We have found that the adsorption of octadecyltrichlorosilane (OTS) monolayers on nanometer-sized silica particles yields a broad blue photoluminescence (PL) with a time scale of nanoseconds. The observed PL intensity increases after curing at temperatures from ∼100 to ∼300 °C,...

    X-ray photoemission, ultraviolet photoemission spectroscopy (UPS), and scanning tunneling microscopy (STM) have been used to determine the energy level alignment and the molecular ordering of monolayer and submonolayer pentacene films on Au(111) in ultrahigh vacuum.

    A new kind of TiO2 (NTA-TiO2(AB)) with single-electron-trapped oxygen vacancies was prepared by the dehydration of nanotubed titanic acid under vacuum. Under visible-light excitation (?ex=420 nm to 650 nm) NTA-TiO2(AB) showed a relatively intense emission, which red shifts with the increase of...

    Structures having a set of planes with submonolayer InAs inclusions in an AlGaAs matrix were fabricated and studied. Lasing was observed as a result of optical excitation. It is shown that lasing takes place via the ground state of excitons localized at InAs islands and may be achieved without...

    We have studied the optical properties of pseudo-alloy monolayer InAs/GaAsN superlattices with highly planar interfaces.

    We describe fabrication and photoluminescence excitation of InGaAs/InP quantum wires with a lateral dimension of ∼350 Å. Transverse confinement results in the splitting of the n = 1 heavy hole-electron transition. Three of these levels are observed in the excitation spectrums The...
