Abstract
We report on the spectroscopic determination of nonradiative host to activator transfer efficiencies in Eu3+-doped Y2O3 and YBO3 under vacuum ultraviolet excitation. The calculation of transfer efficiency is described, and the transfer efficiency behavior of both hosts is assessed in terms of accepted energy flow models. From our measurements we have concluded that electron−hole pair mobility is greater in Y2O3 than in YBO3 and that the primary reason for the relatively low efficiency of Y2O3:Eu3+ under 147 nm excitation is loss of excitation energy to surface states. Measurements on the Tm3+-doped hosts indicate that these properties are features of the host rather than of the dopant.
