摘要: A method for estimating the microscopic probability rate of phonon-assisted energy transfer between rareearth (31) ions in solids was developed based on Dexter’s theory transfer. The proposed this paper enables one to calculate overlap integral from fundamental cross-section spectra nonresonant involving a multiphonon generation both donor and acceptor sites. translation emission spectrum towards absorption scaled with N-phonon represents m-phonon band which performs acceptor. nonvanishing 10 – times smaller than resonant case is found. assisting considered due combined mechanism creation annihilation phonons. participation each phonon process determined. This used investigate Tm(F4)→Ho(I7),Er(I13/2)→@Ho~I7),Tm(F4)] direct transfers LiYF4 crystals, as well back transfers. @S0163-1829~97!00545-6#
