摘要：

The Raman and reflection spectra have been measured on layer crystals PbI2 at room and liquid helium temperatures, respectively. The occurrence of a laser induced 4H double right arrow 2H polytype transition in PbI2 has been observed via the low-frequency shift of the shear-deformation mode in Raman spectrum and the appearance in reflection spectrum a new exciton transition.
