The photoluminescence of a dye embedded in the three-dimensional SnS[sub 2] inverted opal has been studied. Changes of the emission spectrum compared with the free-space dye emission was observed in the stop-band frequency range in accord with reflectance/transmission spectra of this photonic crystal. The angular-dependent component, due to the Bragg stop band, and the angular-independent component, which is, possibly, related to the minimum in the density of photon states, have been distinguished in the dye emission spectrum. © 2001 American Institute of Physics.

    We reveal the effects of microscopic inhomogeneities and the finite laser spot size on the formation dynamics of polariton condensates in CdTe based microcavities. By studying the temporal evolution of polariton photoluminescence (PL), after non-resonant pulsed excitation, both in the far- and...

    We show the dispersion of exciton–polaritons in an all oxide planar resonator structure. A quasi-bulk ZnO film acts as active medium and as cavity. The mirrors are made of Bragg reflectors consisting of ZrO2 and MgO layers. Despite a limited structural perfection, we have observed a giant...

    AWO4 (A=Ca,Sr,Ba) nanofilms are prepared by a self-inventive technique using collodion to disperse nanoparticles and form film, and their photoluminescence (PL) properties are controlled by a nano-TiO2 doping method. This cannot only reach the results of uniform film and PL enhancement, but also...

    Intermixing of AlGaAs-based interfaces is known to be enhanced by capping wafers with a layer of SiO2. Assuming that this enhancement results from the introduction of additional Ga vacancies into the sample, it is possible to obtain the temperature-dependent equilibrium Ga vacancy diffusivity....

    We construct a microscopic model to describe the excited states of poly(2-methoxy, 5-(2′-ethylhexoxy)-p-(phenylenevinylene) in thin film. Within this model, we deduce that in the high energy region, the nature of excited states in the film is very similar to the species observed in...
