Abstract

Luminescence decay curves have been measured from the ⁴S_3/2 excited state of erbium(III) in the elpasolite lattice for a range of concentrations and temperatures. Cross relaxation occurs from this state involving a relaxation at the donor to the ⁴I_9/2 state and a transition at the acceptor from the ground state to the ⁴I_13/2 state. The decay curves are strongly temperature dependent, the cross relaxation becoming important at 80 K and above. A comparison with the decay curves calculated using a shell model of discrete acceptor distribution within the lattice is unsuccessful due to migration of the excitation energy within the lattice.
