Opis:: Optical-temperature investigations of stationary and photo-induced absorption in undoped and Al (or Ga) doped Bi₁₂SiO₂₀ crystals are discussed. In the wave-number range 22000-4000 cm¯¹ under temperatures from 80 to 650 K, peculiarities of thermochromic effect have been revealed and temperature dependences of intensity of bands forming photo- and thermochromic effects have been found. A correlation between these dependences and spectra of thermostimulated current is explained.

Opis:: This paper presents a model of molecular ultrathin crystalline film and analysis of dielectric properties of these spatially very restricted structures. Using the two-time dependent Green functions the energy spectrum and possible exciton states were determined and the dynamic permittivity was calculated. It was shown that the appearance of localized states in the boundary layers of the film depend on the thickness and the changing values of parameters in the border areas of the film. These localized states define schedule and determine the number of resonant absorption lines in the infrared area of the external electromagnetic radiation.
