A SIMPLE KEY FOR FE²�?ZNS CRYSTAL UNVEILED

KLuS two single crystal samples undoped and doped by using a very low (5 %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the form of skinny hexagonal plates. The low phonon Electricity (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples ended up analyzed also by utilizing optical
