We have found that the photoreduction yield from Eu3+ to Eu\*+ depends on excitation wavelength within a single chargetransfer band. The quantum yields 4 were 0.12 k 0.02 (at I93 nm) and 0.06 + 0.0 1 (at 222 nm) in aqueous solution, and 0.42 t 0.07 (at 222 nm) and 0.35 kO.06 (at 248 nm) in methanol
