Luminescent thermometry is a rapidly growing scientific method based on the dependence of the luminescent and spectral characteristics of nano-sized emitters on temperature. The accuracy of this method depends significantly on the theoretical models used to describe the temperature behavior of the spectra. In this paper, we provide a brief overview of our recent results related to new approaches to interpreting the temperature broadening of the spectral lines of single organic molecules in a polymer matrix as a result of electron-­phonon interaction. We believe that the approach under consideration can be successfully applied to a variety of promising emitters used in luminescent thermometry.
