THE 5-SECOND TRICK FOR FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped that has a small (five %) or higher (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the shape of slim hexagonal plates. The small phonon Power (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples have been analyzed also by making use of optical absorption
