EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped with a very low (five %) or superior (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the form of slim hexagonal plates. The minimal phonon Strength (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples have been examined also by utilizing optical absorption an
