Publikováno v: Nanotechnologies in Russia. 7:517-526

Aggregative stable dispersions of particles with anisotropic cores of iron(III) oxyhydroxide and gold or silver nanoshells are synthesized. They feature maximum plasmonic absorption at about 1000 nm (i.e., in the “optical window” of biological ti

Determination of the absorption and scattering cross sections of zinc phthalocyanine nanoparticles

Autor: B. Ya. Kogan, V. S. Dudkin, N. V. Malimonenko

Publikováno v: Optics and Spectroscopy. 116:424-426

The real and imaginary parts of the refractive index of thin zinc phthalocyanine films have been measured by two different methods (spectral and ellipsometric). The results obtained have been used to calculate the absorption and scattering cross sect

Measurement of the absorption coefficient of scattering liquid media by the calorimetric method

Autor: B. Ya. Kogan, A. V. Butenin

Publikováno v: Optics and Spectroscopy. 112:195-197

Using the example of a number of hydrosols (gold nanorods and nanoshells, silver nanoshells, zinc phthalocyanine nanoparticles), we show that the absorption coefficient of a scattering liquid medium can be measured from its heating by a short-time la

Influence of superluminescence on the gain in an active element utilizing organic compounds

Autor: Yu V Ivanov, V. S. Dudkin, V A Pod'yacheva, B Ya Kogan

Publikováno v: Soviet Journal of Quantum Electronics. 20:1079-1083

The influence of superluminescence on the gain in an active element is analyzed using the quasisteady-state approximation. It is shown that total internal reflection in the active-element cell is a factor that severely limits the gain. In the presenc

Nature of cumulative laser damage to optical materials

Autor: B Ya Kogan, A. V. Butenin

Publikováno v: Soviet Journal of Quantum Electronics. 20:187-189

A mechanism explaining cumulative laser damage to optical materials is proposed. This mechanism postulates spatial separation of products of pyrolysis of a material by thermal diffusion in a temperature gradient around an absorbing microinclusion. Th
