Nanophotonics simulation of the spectral characteristics of spontaneous selective fluorescence of two different two-level interacting nanoparticles

The simulation of the spectral characteristics of spontaneous fluorescence associated with the dynamic interaction of two different two-level nanoparticles at the initial excitation of one of them is performed on the basis of solutions of the Schrodinger equations for the amplitudes of incompatible alternatives to the probability of registering the states of a composite system of particles and a quantized radiation field at such photon absorption by the environment that determine the" paths " of its radiation by a particular particle. The dependence of the intensity of such selective fluorescence on the frequency of the detected photon is represented as mutually overlapping contours of 2 pairs of spectral lines reflecting the splitting of the fluorescence lines of non-interacting particles. The contours of the lines differ in the values of their maxima. The figures illustrating these differences are given. The differences in the integral intensity of the contours are compared with the selective settlement of the ground state of each of the particles in the ensemble of the considered particle pairs.
