Abstract
The study of the optical properties of actinide ions is important because of the potential both to discover new optical devices and to test theories that have been developed for lanthanide ions. Optical transitions occur between 5fn orbitals, which have properties similar to the 4fn states of tire lanthanides. The wavefunetions of the 5fn states have a greater spatial extent than those of the 4fn states, so the interaction with the host is stronger in actinides than in lanthanide ions. Thus we expect to observe faster dephasing of excitation in actinides than in corresponding lanthanides.
