Abstract：Ni+ ion was used to replace Cu+ ion in CuAlS2 ternary semiconductor. By use of the crystal-field theory and the structured data of Cu+ site in CuAlS2 crystal, the optical and EPR spectra of CualS2∶Ni+ were calculated. The results are consistent with the observed values.
Key words：Optical spectrum;EPR spectrum;Crystal-field theory;Complex semiconductor;Ni+ ion
