Narrowing of the phonon satellites in the fluorescence spectra of small local excitons

We identified the narrowing of the phonon satellites in the spectra of low-temperature (4.2 °K) fluorescence of small local excitons in isotopically-doped deuteronaphthalenes as a function of depth reduction of the doping level. This new effect is attributed to the partial derealization of the exciton wave function.
