Abstract
Trivalent transition ions associate in pairs when doped in CsCdBr3 cry stals. Using high resolution absorption and emission spectroscopy, we have measured the energy levels of Pr3+ : CsCdBr3 and determined their associated irreducible representations. From Zeeman measurements we o btained the g factor for the 1D2 multiplet (g(parallel-to) = 0.9; g(pe rpendicular-to = 0) and the predictions of a simple crystal field mode l show that Pr3+ ions see mainly an octahedral contribution, plus a sm all C3v distortion. We also use these measurements to determine a valu e of the hyperfine interaction constant A(J)(1D2) of 440 +/- 150 MHz w hich is smaller than the value previously determined for Pr3+ : LaF3.
