Ultra-low luminescence of humid air and its possible role in negative air ion therapy.
One of the unresolved questions related to the mechanism of action of light negative air ions (reactive oxygen species) produced by air ionizers upon humans and animals is transmission of these short-living chemical species upon long distances from the place of their origin. We discovered the phenomenon which may probably resolve this problem. When a thin layer of water hydrating a hygroscopic ...
متن کاملDIRECT LUMINESCENCE AND THERMALLY STIMULATED LUMINESCENCE OF 4H CdI2
Direct luminescence (DL) spectra of 4H Cd12 in the spectral region 1.8-3.4 eV at temperatures between 9.3 and 215 K and thermally stimulated luminescence (TSL) spectra are reported. The DL spectra consist of several overlapping broad emission bands. These bands are due to radiative recombination of localized (trapped) electrons with localized (trapped) holes. With a simple theory, which takes i...
متن کاملLuminescence Properties of TeO2-LiF-Gd2O3 Glasses
In this work, the structural properties and spectroscopic behavior 80 mol.%TeO2-20mol.%LiF glasses which were doped with 0. 05, 0. 2 mole% Gd2O3 have been studied. It was shown that, by increasing the amount of Gd2O3 the glass stability was decreased. The PL emissions at 431nm and 627nm wavelengths were distinguished by 320nm excitation. The FT-IR analysis showed deformed TeO4 groups in these ...
