Influence of Energy Transfer by the Exchange Mechanism on Donor Luminescence
Mitio Inokuti,Fumio Hirayama +1 more
TL;DR: In this paper, the decay of donor luminescence in a rigid solution when modified by electronic energy transfer by the exchange mechanism is treated theoretically, and the rate constant for the elementary process of energy transfer is taken to be of the Dexter form, const exp(−2R/L), where R is the donor-acceptor distance and L is a positive constant.

Spectral Intensities of the Trivalent Lanthanides and Actinides in Solution. II. Pm3+, Sm3+, Eu3+, Gd3+, Tb3+, Dy3+, and Ho3+
TL;DR: In this article, the experimentally determined band intensities in the solution absorption spectra of the trivalent lanthanides were correlated with a theoretical expression derived by Judd, and the spectra were measured in a single medium, dilute acid solution, and, in most cases, in the range ≈6000-50 000 cm−1.
