Optical emission spectroscopy of lead sulfide films plasma deposition.

In-situ Optical Emission Spectroscopy (OES) combined with quantum chemical calculations was used as a powerful tool to find out the exited reactive species existing in plasma discharge during the process of lead sulfide chalcogenide materials deposition. Low temperature nonequilibrium RF (40.68 MHz) plasma at low pressure (0.

Infrared and Raman spectroscopy study of AsS chalcogenide films prepared by plasma-enhanced chemical vapor deposition.

AsS chalcogenide films, where As content is 60-40at.%, have been prepared via a RF non-equilibrium low-temperature argon plasma discharge, using volatile As and S as the precursors. Optical properties of the films were studied in UV-visible-NIR region in the range from 0.

Investigation of the composition-structure-property relationship of AsTe films prepared by plasma deposition.

AsTe amorphous films of different chemical content were prepared by Plasma-Enhanced Chemical Vapor Deposition (PECVD). For the first time the optical properties of As-Te chalcogenide materials have been measured in UV-VIS-IR ranges (from 0.2 to 25μm) for a very wide range of chemical compositions (20-80at.

[Fasting diet therapy in gastrointestinal tract diseases].

The article is devoted to an effective not medicamentous method of therapy--to the medical starvation. Indications and contra-indications to carrying out of medical starvation are given. Own results of use of medical starvation are resulted at diseases of bodies of digestion.

[Clinical-functional state of the retina and optic nerve in contusions of the eyeball].

The function of the retina and optic nerve was studied in 79 patients with contusions of the eyeball of various severity. A complex electrophysiological method was used, consisting of recording of visual evoked potentials and of the general and macular electroretinograms, assessment of the threshold electrical sensitivity and lability. Changes were detected in all the layers of the retina and optic nerve, the degree of these changes augmenting with the severity of injury.
