WebWhen the luminescence decay times after direct excitation of a level are also measured, ϕ UCsat for that level can be calculated. This approach is tested on a series of PbF 2:Yb 3+,Er 3+ crystals. Good agreement between the estimates obtained as above and the directly experimentally measured ϕUCsat values is demonstrated.
