FASCINATION ABOUT FE²�?ZNS CRYSTAL

KLuS two single crystal samples undoped and doped using a very low (5 %) or high (38 %) concentration of trivalent thulium or ytterbium ions were being synthesized in the shape of thin hexagonal plates. The lower phonon Power (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples were analyzed also by using optical absorption a
