XANES ANALYSIS OF L-3,L-2 EDGES OF ZINC SELENIDES WITH TRANSITION-METALS

X-ray Absorption Near Edge Structure (XANES) for ternary compounds Zn1 -xTMxSe (TM=Cr, Mn, Fe, Co, and Ni) with different concentration x of transition metals (TM) has been studied with the use of synchrotron ra diation. XANES measurements were carried out in the fluorescence detec tion mode using synchrotron radiation from the HE-PGM2 plane grating m onochromator at BESSY. The L-3.2 edges for Se, Zn and different transi tion metals (Cr, Mn, Fe, Co, and Ni) in Zn1-xTMxSe compounds have been analyzed. Moreover, the analysis of L-3.2 edges for different transit ion metals in binary TMSe has also been made. The characteristic featu re of L,, edges for transition metals containing two white lines was o bserved. The energy positions of these maxima are in good agreement wi th the theoretical results. The studies of L-3.2 edges of Se in ternar y compounds in comparison to the same edge of host crystal (ZnSe) allo wed us to obtain information about the influence of additional 3d-stat es of TM on the density of states of ternary compounds.
