The four-component complexes of rare-earth ions with Chromazurol S (CAS), 1, 10-phenanthrolin (phen) and cetyltrimethylammonium bromide (CTMAB) have been investigated. The absorption magirnum of yttrium complex is at 632 nm, and the values for lanthanides except lanthanum are in the region of 630-632 nm.
