A history of the development of selective laser spectroscopy of ions and molecules in crystalline and amorphous matrices is presented beginning from a pioneering work by Yu.V. Denisov and V.A. Kizel in 1967, who were the first to demonstrate the possibility of removing the inhomogeneous broadening of luminescence spectra of impurity ions in glasses upon monochromatic resonance excitation. The methods of selective spectroscopy are based on spectroscopy of optical zero-phonon transitions in impurity centers in solids. The fundamentals of zero-phonon transition spectroscopy are considered and the mechanism of removing the inhomogeneous broadening of optical spectra of ions and molecules in crystals and amorphous solids under selective laser excitation of luminescence and persistent hole burning in absorption spectra is presented. Various applications of selective laser spectroscopy for fundamental and applied studies are discussed.

Keywords: zero-phonon lines, selective excitation of luminescence, persistent hole burning, impurity molecules and ions, crystalline and amorphous matrices, homogeneous and inhomogeneous optical line broadening, optical dephasing, vibrational relaxation, spectral diffusion, exciton localization
