Abstract

Temperature dependence of spectral and temporal behaviors of resonant emission in NaNO₂ has been investigated under the excitation of the isotopic ¹⁵NO₂-molecule. It has been found that time response of the exciton line includes a rise component and can be interpreted by taking account of the transfer from the isotopic level. Time-resolved spectra of the exciton line under the excitation of the isotropic molecule shows broadening with the evolution of time. Spectral and temporal behaviors of the line reflect the transfer from the isotopic level as well as the thermalization of the excitons within the exciton band.
