Shift of Infrared Absorption and Emission Spectra of Transition Metal Ions in Solid Solutions of Semiconductor Compounds
S. V. Naydenov
A universal theoretical model is proposed that explains the observed shift of IR absorption and emission bands in the spectra of transition metal ions in solid solutions of semicon…
Improved efficiency of planar light converters based on Al2O3-YAG:Ce eutectic crystals: Physical Trends and Limits
S. V. Naydenov, O. M. Vovk, Yu. V. Siryk +2
A theoretical model of a crystalline converter of white light with internal scattering medium is proposed. Obtained are the expressions for estimation of the light converter effici…
Dispersions of multi-walled carbon nanotubes in liquid crystals: new challenges to molecular theories of anisotropic soft matter
Longin N. Lisetski, Nikolai I. Lebovka, Sergei V. Naydenov +1
Aggregation of carbon nanotubes dispersed in nematic liquid crystalline medium is discussed. A model is proposed, which assumes that the aggregates consist of a "skeleton" formed b…
Complex light with optical singularities induced by nanocomposites
V. V. Ponevchinsky, M. S. Soskin, A. I. Goncharuk +3
The nonocomposites on the base of long (5-10 m, -MWCNTs) and short (2 m, -MWCNTs) multi-walled carbon nanotubes (MWCNTs) hosted by nematic 5CB were investigated in…
Detection of organic materials by spectrometric radiography method
S. V. Naydenov, V. D. Ryzhikov, G. M. Onyshchenko +2
In this paper we report a spectrometric approach to dual-energy digital radiography that has been developed and applied to identify specific organic substances and discern small di…
