FE²�?ZNS CRYSTAL FUNDAMENTALS EXPLAINED

KLuS two one crystal samples undoped and doped having a minimal (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions were being synthesized in the shape of thin hexagonal plates. The minimal phonon Vitality (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples had been analyzed also by using optical absorption and
