A SIMPLE KEY FOR FE²�?ZNS CRYSTAL UNVEILED

KLuS 2 one crystal samples undoped and doped which has a lower (5 %) or significant (38 %) concentration of trivalent thulium or ytterbium ions were being synthesized in the shape of slender hexagonal plates. The lower phonon Strength (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples had been studied also by utilizing optical
