A SECRET WEAPON FOR FE²�?ZNS CRYSTAL

KLuS two single crystal samples undoped and doped using a small (five %) or large (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the shape of slim hexagonal plates. The low phonon Vitality (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples had been studied also through the use of optical abs
