Measurements have been made of the radiative properties of porous silicon obtained by anodic etching of plasma-processed p-type single-crystal silicon (100). It is found that the photoluminescence intensity of the test samples is significantly greater than that of porous silicon obtained on the surface of single-crystal silicon with no plasma preprocessing. © 2014 Optical Society of America.

This paper discusses the luminescence properties of anodized porous silicon with various degrees of oxidation. The effect of laser excitation and photostimulated anodization on the photoluminescence intensity of porous silicon is considered. A model is proposed for photoluminescence in porous silicon. © 2013 Optical Society of America. Source

This article contains the results of a study of the induced birefringence in a lithium niobate crystal when it is introduced into an inhomogeneous electric field. The induced-birefringence distribution surfaces over the entire cross section of the crystal are presented. © 2010 Optical Society of America. Source

The thermal action of the radiation that appears as a result of the Dufour effect when a transparent disperse medium is irradiated is theoretically analyzed. Analytical expressions are obtained that describe the dynamics of the nanoparticle concentration and the temperature of the medium. © 2013 Optical Society of America. Source

The angular-distribution parameters of the photoinduced scattering of light at a wavelength of 476.5 nm are used to determine the photovoltaic and diffusion field in nominally pure single crystals of stoichiometric composition (R = Li/Nb = 1), grown from the melt with 58.6 mol% LiO2 (LiNbO3 stoich.), in nominally pure single crystals of congruent composition (LiNbO3) in congruent single crystals doped with Cu2+, Zn2+, Gd3+, Y3+, Er3+, B3+, (Cu2+ + Gd3+), and (Ta5+ + Mg2+). The photoinduced variations of the refractive index of the crystals are determined. © 2015 Optical Society of America. Source
