DETAILS, FICTION AND FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped that has a reduced (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the form of slim hexagonal plates. The low phonon Vitality (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples have been researched also by utilizing optical absorption
