FASCINATION ABOUT FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped with a small (5 %) or large (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the form of thin hexagonal plates. The lower phonon Electrical power (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples have been studied also by utilizing optical absorption and
