Multiphonon-assisted anti-Stokes and Stokes fluorescence of triply ionized rare-earth ions. Auzel, F. Physical Review B, 13(7):2809--2817, April, 1976.
Multiphonon-assisted anti-Stokes and Stokes fluorescence of triply ionized rare-earth ions [link]Paper  doi  abstract   bibtex   
Experimental demonstration of multiphonon-assisted anti-Stokes and Stokes excitation of rare-earth ions (R3+) in different hosts, that is, in a weak-coupling ion-lattice interaction case, is obtained. An exponential behavior of excitation probabilities with respect to energy difference between excitation and electronic line is found, just as for multiphonon-assisted nonradiative decay and energy transfer. Exponential parameters αAS and αS for anti-Stokes and Stokes excitation are measured and linked to the Miyakawa-Dexter α parameter for decay, leading to estimates for Pekar-Huang-Rhys coupling parameter S0 of about 0.04, in agreement with values obtained from one-phonon spectra or nonradiative-decay measurements. A semiempirical formula is deduced to obtain α from only one parameter, an effective phonon energy.
