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

KLuS two single crystal samples undoped and doped with a reduced (five %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the form of thin hexagonal plates. The very low phonon Strength (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples ended up analyzed also by using optic
