EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped which has a reduced (five %) or higher (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the form of thin hexagonal plates. The very low phonon Strength (�?20 cm ⁻�?) was verified employing Raman spectroscopy. Samples have been analyzed also through the use of optical absor
