Near-band edge photoluminescence in CuGaS2 has been measured at room temperature. It has been found that the green emission at 2.454 eV is strongly polarized parallel to the c-axis. In addition, a new emission peaked at 2.55 eV has been observed with the polarization perpendicular to the c-axis. These emissions are discussed in terms of the optical selection rule and exciton energies.
