A SIMPLE KEY FOR FE²�?ZNS CRYSTAL UNVEILED

KLuS 2 solitary crystal samples undoped and doped by using a very low (5 %) or large (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the shape of slender hexagonal plates. The low phonon Strength (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples had been examined also through the use of optical
