A theoretical study of spectral profiles near the Kr and Xe resonance lines of the 1,3P1–1S0 transitions produced in the atmosphere of helium under equilibrium conditions is performed. Potential energy curves for the excited states of the Kr(4p55s)+He and Xe(5p56s)+He quasimolecules are obtained in the framework of the consistent use of the effective Hamiltonian method and the pseudopotential method. For the ground state experimental data are used. Based on quasistatic approach the spectral profiles of the quasimolecular absorption and radiation in the short-wave region of the resonance lines are calculated by applying the potential energy curves obtained. The resulting profiles are compared with experimental ones.

The proposed method of synthesis of CQDs on the basis of nanoporous carbon obtained from plant raw materials. It is established that in the short-wave region a band is registered, which is due to the exciton mechanism of recombination, whereas in the long-wavelength region it is related to the state of defects. The kinetics of PL extinction is not strictly exponential, which most likely indicates the distributed nature of fading from individual emitters.
