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

KLuS two single crystal samples undoped and doped using a small (five %) or high (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the shape of thin hexagonal plates. The low phonon Strength (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples ended up studied also by using optical absorption
