Description
Photo-redox reactions of lanthanide and actinide ions are expected to be utilized for nuclear fuel reprocessing and partitioning of high level wastes. One of model systems is photo-reduction of Eu3+ to Eu2+ in solution. The photo-reduction yields in alcoholic solution have been measured by the method of nanosecond laser photolysis. The highest yield was 0.97±0.16 in methanol at 308 nm excitation. Within a single charge-transfer band, shorter wavelength excitation showed higher yield. Two-photon reduction via f from f transitions has been found. (author)
