摘要	The EPR zero-field splitting D and g factors g(parallel to), Delta g ( = g(parallel to) - g(inverted perpendicular)) for Co(2+) ions at Ag(+) and Ga(3+) sites of sulphur-annealed AgGaS(2) crystal were calculated from the high-order perturbation formulas based on the two spin-orbit coupling parameter model. The calculated results show that Co(2+) replace Ag(+) site in the AgCaS(2) crystal. This point is contrary to that obtained from the absorption spectrum and Raman spectroscopy studies for Co(2+) in as-grown AgGaS(2) crystal. It appears that Co(2+) can replace Ag(+) or Ga(3+) site in AgGaS(2) ternary semiconductor, depending on the technology of material preparation. (C) 1998 Published by Elsevier Science Ltd.
