The photoluminescence of Mn-activated RbCdF3 shows a Mn2+ emission band at 560 nm; the corresponding excitation bands are between 240 and 520 nm. After X-irradiation an increased Mn2+ emission can be observed and the excitation spectrum shows an additional broad intense band at 300 nm. Upon excitation at 300 nm the intensity of the Mn2+ emission decreases, whereas excitation at 240 nm leads to an increase in the PL intensity. Electron paramagnetic resonance shows that the number of Mn2+ ions is reduced upon X-irradiation; the original Mn2+ level can be restored upon optical bleaching. (© 2007 WILEY-VCH Verlag GmbH & Co.
