Opis:: We report results of investigation on the fluorescence induced in sodium vapour by pulses of laser light tuned near the 3S → 4P transition (330 nm). The fluorescence was observed in perpendicular and parallel directions in respect to the laser beam. A depletion of fluorescence intensity corresponding to the 5D → 3P transition (498 nm) was observed along the laser beam. We explain this effect as a result of reabsorption that is caused by intense population of the 3P level due to cascade stimulated processes. The most intense depletion occurs about 20 ns after the laser pulse and it corresponds to the moment of maximal population of the 3P level.

Opis:: GaAs:C crystal was grown by liquid encapsulated Czochralski technique with large partial pressure of CO in ambient atmosphere p$\text{}_{CO}$/p$\text{}_{tot}$ = 0.2 and investigated using near and infrared absorption, photoluminescence, photoconductivity, photo-induced current transient spectroscopy and photo-Hall measurements. High resistivity of the crystal was found in electrical measurements (10$\text{}^{7}$ Ω cm, the Fermi level at 0.67 eV below conduction band at 300 K). Local vibrational mode revealed increased concentration of carbon acceptor and presence of oxygen related complexes. Photoluminescence spectra were dominated by two bands with peak energies at 1.49 eV and 0.8 eV. The near band gap emission shifts with excitation intensity up to 4 meV/decade. In photocurrent spectrum a strong photoionization band with E = 0.55 eV is observed.

Opis:: Nanoparticles of chalcopyrites copper indium gallium sulfide ($CuIn_{x}Ga_{1-x}S_{2}$ or CIGS) and copper indium gallium selenide ($CuIn_{x}Ga_{1-x}Se_{2}$ or CIGSe) were fabricated sonochemically. They were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, high resolution transmission electron microscopy, selected area electron diffraction, and diffuse reflectance spectroscopy. The electrical and photoelectrical properties of the fabricated nanomaterials were investigated.
