ABSTRACT
We report on crystalline pyramidal structures grown via self-organization on the rubrene (001) surface. The analysis of their spectral response by means of photoluminescence with micrometer lateral resolution reveals an intensity enhancement on-top of the surface structures. As we demonstrate this intensity increase can be related to the excitation processes at the molecular level in combination with exciton confinement within the pyramids.

    We have systematically studied the optical properties of Zn[sub x]Cd[sub y]Mg[sub 1-x-y]Se alloys using photoluminescence (PL) and photoluminescence excitation. It is shown that, at low temperatures, PL is dominated by excitons localized by potential fluctuations, which become stronger with...

    It is shown experimentally that the exciton luminescence (λ = 172 nm) quantum yield excited by excess electrons drifting through solid xenon at 77 K in fields of 10 kV/cm amounts to 20 ± 5 per electron and that luminescence takes place during the entire drift process. A CW bulky discharge...

    Abstract. Photoluminescence (PL) measurements under different excitation powers were carried out at low temperature on tensile-strained In[sub 0.3]Ga[sub 0.7] TAS single wells of 6 nm with InGaAs barriers lattice matched to InP substrate. PL measurements taken at 2 K show a main emission band at...

    The time dependence of the Zeeman-sublevel anticrossing signal in triplet-bound exciton emission from gallium selenide has been investigated under resonant excitation conditions. It has been found that the shape of the anticrossing signal varies during the lifetime of the excited state. The time...

    Data on the VUV and UV cathodoluminescence spectra of the Kr-based solid solutions, Kr-D2, Kr-D2-O2, and Kr-Xe-O2, as functions of dopant concentration are presented. Introducing deuterium impurity into krypton crystals produces no new spectral features, which indicates that electron bombardment...

    We observe for the first time two excited states of the 78-meV acceptor in liquid encapsulated Czochralski GaAs with excitation energies of 62.9 and 66.9 meV above the ground state, respectively. These levels were observed in two different samples using selective excitation luminescence and...

    The luminescence properties of CaF2 nanoparticles with various sizes (20-140 nm) are studied upon the excitation by VUV and x-ray quanta in order to reveal the influence of ratio of mean free path and thermalization length of charge carriers and nanoparticle size on the self-trapped exciton...
