RUMORED BUZZ ON FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped with a minimal (five %) or large (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the shape of skinny hexagonal plates. The minimal phonon Strength (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples were being studied also through the use of optic
