This review addresses the energy transfer processes involving lanthanide ions, analysing in particular the case of the Tb3+→Eu3+ energy transfer processes in terbium-based materials containing Eu3+ as a dopant. These examples are used as case studies for the processes and mechanisms concerning energy transfer generally involving Ln3+ ions, pointing out the differences caused by the structural characteristics of the host. The review introduces the theoretical background of the energy transfer processes, providing a brief description of the possible regimes for the donor-acceptor transfer depending on the donor concentration, together with the general considerations on the specific case of Tb3+→Eu3+ transfer. The review is completed by a brief survey of the literature published on this topic from the 60s to date, including some of the most recent papers.

Abstract
This review addresses the energy transfer processes involving lanthanide ions, analysing in particular the case of the Tb3+→Eu3+ energy transfer processes in terbium-based materials containing Eu3+ as a dopant. These examples are used as case studies for the processes and mechanisms concerning energy transfer generally involving Ln3+ ions, pointing out the differences caused by the structural characteristics of the host. The review introduces the theoretical background of the energy transfer processes, providing a brief description of the possible regimes for the donor-acceptor transfer depending on the donor concentration, together with the general considerations on the specific case of Tb3+→Eu3+ transfer. The review is completed by a brief survey of the literature published on this topic from the 60s to date, including some of the most recent papers.File | Dimensione | Formato | |
