DETAILS, FICTION AND FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped with a lower (five %) or large (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the form of slender hexagonal plates. The very low phonon Power (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples have been analyzed also by utilizing optical absorpti
