Far-field fluorescence spectromicroscopy of single quantum emitters (SQE) (organic molecules, quantum dots, color centers in crystals) is one of the actively developing fields of modern photonics, which is widely demanded in various applications in physics, chemistry, material sciences, life sciences, quantum technologies. In this paper we present a description of multifunctional experimental setup, which was developed last years in the Institute for Spectroscopy of the Russian Academy of Sciences. It allows to measure optical spectra and fluorescence images of SQE, as well as their temporal behavior and luminescence kinetics, in a broad range of temperatures (from cryogenic to ambient). It is shown that spatial coordinates of SQE can be reconstructed with subdiffractional accuracy (up to a few Angstroms). Some examples of the developed methods for multiparameter superresolution microscopy (nanoscopy) of materials and nanostructures are presented.
