HELPING THE OTHERS REALIZE THE ADVANTAGES OF FE²�?ZNS CRYSTAL

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