Luminescent thermometry is a rapidly growing scientific method based on the dependence of the luminescent and spectral characteristics of nano-sized quantum emitters, QE (organic molecules, semiconductor quantum dots, color centers in nano-/microcrystals, nanoparticles) on temperature [1]. There are different approaches to reconstruct temperature of QE local environment, namely, position and/or width of spectral peaks, ratio of amplitudes of different spectral peaks. The techniques of luminescent nanothermometry with QEs became to be much more powerful when use luminescence imaging - nanoscopy with reconstruction of spatial coordinates with extreme high accuracy (up to size of emitters, i.e. nanometers), thus realizing the idea of multiparameter optical nanoscopy [2]. Even all three spatial QEs coordinates can be reconstructed using adaptive optics techniques, for example double helix point spread function [3]. The accuracy of all methods 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 on single QEs spectroscopy and nanoscopy: single organic molecules [1,2,4], colloidal semiconductor quantum dots [5-7], color centers in CVD and HPHT diamonds [8-10].
We bring especial attention 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.
