Abstract: The intensity ratios, I Lk/I L? (k=l,? 1,4,? 3,6,? 2,7,9,10,15,? 1,5,? 2,3,? 4,?,?), have been measured for some compounds of 66Dy, namely, Dy 2O 3, Dy 2(CO 3) 3, Dy 2(SO 4) 3, DyI 2 and Dy metal by creating the L i(i=1-3) sub-shell vacancies in widely different proportions at two incident photon energies of 22.6keV and 59.54keV, in order to check the predicted dependence of these ratios on the incident photon energy and also investigate the influence of chemical effects on these ratios for an f-block element. The measurements were performed using the EDXRF spectrometer involving disk type radioactive sources of Cd 109 and Am 241 and a Peltier cooled Si PIN x-ray detector arranged in the 90° reflection geometry. The measured intensity ratios have been compared with the theoretical I Lk/I L? values and those calculated using the two sets of fluorescence and Coster-Kronig yields available in literature in order to check the reliability of the theoretical/calculated values. Further, the measured ratio, I L?4/I L?, was found to depend on the oxidation state of 66Dy as well as nature of ligand attached to it in a given compound. © 2012 Elsevier Ltd.
