A sharp luminescence line due to the crystal-field transition (^4T_1-^6A_1) of Fe^<3+> in the tetrahedral symmetry is observed for the first time in iron-doped I-III-VI_2 chalcopyrite type compounds, CuGaS_2 and CuAlS_2. The peak energy is 4,942 cm^<-1>and 5,804 cm^<-1> respectively. These values are rather small as compared to those in many ferric oxides in which the excitation energy of ^4T_1 in octahedral symmetry is observed around 10,000 cm^<-1>. The Zeeman effect is also observed and is explained quantitatively by the use of the ligand field theory: We find that g_&bottm; of the lowest excited state is zero and the spin-orbit parameter 18 cm^<-1>.
