Abstract
Energy transfer studies have been made in terbium-europium-doped zinc phosphate glass at room temperature. Enhancement of the Eu3+ (D-5(0) - -> F-7 manifold) emission and a decrease in the Tb3+ emission (D-5(4) --> F-7 manifold) have been observed as a result of energy transfer fr om Tb3+ ions to europium ions. The energy transfer mechanisms have bee n found to be mainly electric dipole-dipole in nature. The energy tran sfer efficiencies, transfer probabilities and average donor-acceptor d istances have been calculated.
