The photoluminescence (PL) spectra of AgInS2 crystals grown by a hot-press method have been investigated by confocal microspectroscopy. The two-dimensional image of PL intensity, which shows an area of the chalcopyrite and orthorhombic structures, with a high resolution of micrometer order was obtained. The free-exciton and biexciton emissions on the chalcopyrite structure were clearly separated. Furthermore, the temperature dependence of band-gap energy was analyzed. © 2011 The Japan Society of Applied Physics.
