Absorption and Spontaneous Emission of Light by Molecules Near Metal Nanoparticles in External Magnetic Field

The frequency dependence of dipole polarizabilities of diamagnetic metal nanoparticles in a constant magnetic field B of various values is investigated. It is shown that with change of a magnetic field induction optical spectrums of absorption, scattering and radiation of nanosystems are transformed. It occurs as for nanoparticles, and molecules located near a surface of these particles. Influence of a magnetic field on absorption rate of photons by a cluster “molecule-nanoparticle”, and also on the rate of spontaneous radiation a molecule near a nanoparticle is established.
