EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS 2 one crystal samples undoped and doped using a small (5 %) or significant (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the shape of slender hexagonal plates. The small phonon energy (�?20 cm ⁻�?) was verified using Raman spectroscopy. Samples were being studied also by making use of optical absorpt
