EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS two solitary crystal samples undoped and doped using a low (5 %) or large (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the shape of slender hexagonal plates. The small phonon Vitality (�?20 cm ⁻�?) was verified employing Raman spectroscopy. Samples have been analyzed also by making use of optical ab
