5 SIMPLE TECHNIQUES FOR FE²�?ZNS CRYSTAL

KLuS two single crystal samples undoped and doped having a lower (5 %) or high (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the shape of thin hexagonal plates. The low phonon Electrical power (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples were researched also by utilizing optical abso
