A possible mechanism of the photoinduced luminescence degradation in the hexagonal CdSxSe₁₋x quantum dots synthesized in a glass matrix is discussed using luminescence decay kinetic investigations and ab initio calculations ...

Noise-induced escape from the metastable part of potential is considered on time scales preceding the formation of quasiequilibrium within that part of the potential. It is shown that, counterintuitively, the escape flux ...

Ellipsomety examination of dielectric sheetings and measured of reflection spectrum at normal incidence there carried out. A film of Al₂O₃ on a surface of copper mirrors of a diamond microgrinding was deposited. The thickness ...

We propose the theory of the micro-domains (MD) formation in ferroelectric photorefractive crystals appeared under steady illumination by laser beam perpendicular to the polar axis. The crystal has the donor level made ...

The evolution of time-resolved photoluminescence (PL) spectra in Au-doped nanocrystalline silicon films produced by laser ablation has been studied. The PL spectra with a relaxation time of nanoseconds are broad; they lie ...

Si-rich SiO₂ films prepared by r.f. magnetron sputtering and annealed at 1150 °C are investigated by photoluminescence, Raman and EPR methods. It is found that emission spectrum of as-prepared samples contains one broad ...

Physical peculiarities of the equilibrium thermal radiation have been considered within the black body model for the case of ultimate restrained photon flows inside an ideal ("lossless") optical communication channel. ...

Linear dichroism induced by uniaxial compression strain in semiconductor silicon samples was studied with modulation spectroscopy technique using modulation of electromagnetic radiation polarization. We obtained a spectral ...
