The substitutional sites of Co2+ ions in Co2+-doped CuG(1-x)Al(x)Se(2) (including CuGaSe2 where x = 0 and CuAlSe2 where x = 1) semiconductors are studied by analyzing the composition x dependence of optical spectral parameters reported in the previous literature for these materials. From the studies, we suggest that Co2+ occupy I-group cation site rather than III-group cation site. The suggestion is discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.
