A complete diagram of the Stark sublevels of Pr3+ for the P0,1;1D2;3F2,3 terms has been constructed on the basis of a study of the absorption and luminescence spectra of CaWO4 crystals containing Pr3+. Strong splitting of the Pr3+ terms in the environment examined has been established. © 1969 The Faraday Press, Inc.
