FASCINATION ABOUT FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped with a low (five %) or higher (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the shape of slender hexagonal plates. The minimal phonon Power (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples had been analyzed also by utilizing optical absorption a
