Abstract

The low temperature spectra of absorption and luminescence of a wide variety of impurity doped organic and inorganic solids comprise very narrow (io 1O cm1) and intense zero-phonon lines (zPL). They arise from the purely electronic transistions in the impurities i.e. from the changes of the electronic state not accompanied by creation or annihilation of the phonons of the host solid. (ZPL may be called the optical analog of the M5sbauer line), Because of their narrowness ZPL's are very sensitive to even very slight differences in the crystal fields at the 1oca tions of impurities and the ZPL spectruim of a body of impu.rities displays a large inhomogeneous broadening (formula available on paper).
