THE GREATEST GUIDE TO FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped that has a minimal (5 %) or superior (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the shape of slender hexagonal plates. The minimal phonon energy (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples had been researched also by utilizing optical
