Boiling occurs in a solution of oxygen and fullerenes in CCl4 upon optical pumping of C60 upon the fast appearance of incandescent fullerenes in cold solvent. Upon single-photon absorption, a spherical zone of the critical state of CCl4 is formed wit

The luminescence of singlet oxygen at wavelengths of 760 and 1270 nm in solutions of fullerene in aerated organic liquids irradiated by high-power short laser pulses and by xenon lamps is considered theoretically. The obtained analytical formulas all

The possibility of creating femtosecond optical switches based on fullerene-containing media is studied numerically. Two approaches to the problem are considered, namely, a film of a fullerene-polymer solid solution and a fullerene film obtained by v

A kinetic model of the photodynamic fullerene-oxygen action on biological tissues is developed. The efficiency of generation of singlet oxygen is studied in relation to the intensity of exciting radiation and the concentrations of fullerene and oxyge

The stimulated scattering by fine-scale refractive index inhomogeneities in fullerene-containing media is theoretically investigated. The stimulated scattering can lead to a significant attenuation of the far field axial intensity of the passed beam
