The lecture discusses the experimental technique of fluorescence spectromicroscopy of single molecules, and quantum emitters in general, the history of the development of this field, as well as applications for studying the photo-physical properties of colloidal semiconductor quantum dots (QDs), organic single molecules (SMs), color centers in diamonds, incl. at cryogenic temperatures. The microscopic nature of the blinking photoluminescence effect of single QDs, the results of studies of local field effects, as well as the processes of spectral diffusion and electron-phonon coupling in impurity polymer media with quantum dots and organic molecules are considered. The results of a comparative analysis with data obtained by other methods (photon echo, Raman scattering, electron microscopy) are presented. The capabilities of the three-dimensional (3D-) fluorescence nanoscopy technique implemented according to the scheme of the double-helix point spread function (DHPSF) with the use of adaptive optics tools are demonstrated.

The lecture presents the results obtained by the team of authors of the Leading Scientific School of Russia headed by RAS Corr. Memb. A.V. Naumov (NSh-776.2022.1.2, www.single-molecule.ru). Researches were supported by State Contract of MPGU (AAAA-20-120061890084-9).
