EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS two single crystal samples undoped and doped having a low (5 %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of slim hexagonal plates. The reduced phonon Strength (�?20 cm ⁻�?) was verified making use of Raman spectroscopy. Samples were being researched also by using optical
