Abstract
We present the first spectroscopic investigation concerning the role of four ions (Ru, Rh, Os, Re) of the platinum group on the photochromic behavior of the photorefractive crystal Bi12SiO20. Absorption and magnetic circular dichroism (MCD) spectra were taken in the thermally bleached state and after various illuminations so as to determine the coloration thresholds. Ruthenium and Osmium are demonstrated to enter the crystal, whereas the answer is not yet certain in the case of rhodium and rhenium. We believe that the doping occurs at the pseudo-octahedral Bi site.
