摘要：

High quality amorphous CuCl films were obtained which are completely transparent below the absorption edge and show a sharp crystallization behaviour near 177 K. On annealing at various temperatures, the quantum size effect of excitons was observed in both the amorphous and the crystalline phases, with the confinement size being increased with increasing annealing temperature. In the amorphous phase the excitons are confined within a size defined by the short-range order, whereas grain boundaries in the crystalline phase provide confinement potential barriers.
