Abstract:

The spectroscopic study of GdA103 doped with Cr3 between 2 and 300 K revealed a structure to the R lines which is described by a ferro-magnetic exchange interaction with the Gd3 ions, with J 2.1 reciprocal centimeters for the ground state and J 3.2 reciprocal centimeters for the excited state of Cr3. The selection rules on the transitions are qualitatively discussed in order to explain the change in the fluorescence spectrum between 2 and 4 K. The fluorescence lifetime is 9.0, 15.4, and 18.0 ms at 2.0, 4.2, and 77 K respectively.
