N2 - The transmittance, luminescence, and Raman spectra in PbI2 microcrystals of 2H polytype, grown in the voids of alkali-borosilicate glasses (void dimensions 4-30 nm), are investigated. Depending on the conditions of growth, the exciton states of the microcrystalline systems were found to shift toward higher energies by 35-60 meV relative to the free exciton energy in bulk single crystals as a result of the quantum-well effect. The resonant Raman spectra of PbI2 microcrystals exhibit not only the conventional Raman component AIg, but also components associated with the appearance of the Eu and A2u optical phonons and the two-phonon processes.
