Abstract

Micro-structure of AgInS2 grown by the hot-press method has been examined by the properties of free-exciton emission using a scanning confocal-microscopy system. The crystal structures are distinguished by a two-dimensional image of free-exciton emission at RT. The excitonic emissions with the orthorhombic structure were also analyzed and a bound exciton emission was observed in addition to a free exciton emission. Furthermore, it is indicated that the two-dimensional image of decay-time constant is more insusceptible to resolve the structures than that of emission intensity. (© 2013 WILEY-VCH Verlag GmbH & Co.
