Long-term evolution of luminescent properties in CdI₂ crystals

Анотація:

Fresh and aged melt-grown or gas-phase grown CdI₂ crystals are studied by means of low-temperature photoluminescence spectroscopy. Noticeable transformations of emission spectra are observed after long-term aging. The formation of nanostructures containing cadmium oxide and cadmium hydroxide as well as the changes in local surrounding of iodine atoms and the possible growth of polytypic modifications of CdI₂ are taken into account when considering the diversity of optical spectra.
