PbI_2/CdI_2 superlattices (multi-quantum well) have been grown by a hot wall epitaxy. Characteristic peaks due to a long period of superlattices appear on X-ray diffraction patterns. From the analysis of these patterns, thicknesses of both PbI_2 and CdI_2 layers of prepared samples are identified. Optical measurement shows that exciton transition energies in PbI_2/CdI_2 superlattices shift to the higher energy side with the decrease in thickness of PbI_2 layer. The analysis of this shift by the variational calculation of exciton and the observation of strong exciton peaks indicate PbI_2/CdI_2 superlattices belong to the type I superlattice.
