In this work, we study the relation between the widths of the zero-phonon lines (ZPL) of single impurity molecules (SM) in solid matrices with local effective values of the refractive index n. Since at ultralow temperatures the width of SM ZPL is determined mainly by the radiative lifetime T1, while the local-field effects produce the function T1(n), SM spectroscopy makes it possible to measure the distribution of n local values in solids. The approach proposed here for studying local fluctuations of n has been tested on the example of doped polymers and molecular crystals.
Key words: single-molecule / super-resolution / local-field / zero-phonon line / refractive index / fluctuations / polymer / molecular crystal
