The complicated spectrum of radiative transitions in sillenite-type crystals is investigated. It is shown that the luminescence excitation spectra (LES) of crystals studied can be divided into three groups: a) the excitation in the fundamental absorp

In sillenite-type crystals at low temperatures the phenomena of effective laser modulation of the photochromic effect (LM PCE) previously investigated in steady-state conditions are found. The lack of effects of spatial excitation transfer during PCE

Seventy-one patients with volvulus of fatty appendix of the colon (sigmoid colon--52 patients, caecum--12, ascending colon--5, vermicular appendix--2 patients) were treated. Volvulus of epiploic appendix was seen in 67.6% operated patients, inflammat

The aim of this paper is the study, by thermally-stimulated current (TSC) techniques, of the localized levels present in the forbidden gaps of germanium—(BSO), silicon—(BSO), and titanium—(BTO) sillenite-type non linear crystals. Also crystals

Temperature-modulated absorption spectra of SbSI near the ferroelectric-paraelectric phase transition are reported. The experiment was performed using unpolarized light. The modulation technique allows a more precise and univocal determination of the

Using electroreflection and thermoreflection methods the energy spectrum of elections in the fundamental absorption edge of SbSI for two polarizations was investigated.The reflection spectra obtained have a complicated structure and a strong anisotro

Measurements of the absorption coefficient of semiconductive materials are terminated on the high photon energy side by the low transmission level in even the thinnest available crystals. The aim of this work is to overcome this intrinsic limitation
