RUMORED BUZZ ON FE²�?ZNS CRYSTAL

KLuS two solitary crystal samples undoped and doped by using a low (5 %) or superior (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of slender hexagonal plates. The minimal phonon Strength (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples were analyzed also through the use of optica
