THE SINGLE BEST STRATEGY TO USE FOR FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped using a lower (5 %) or higher (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the shape of slim hexagonal plates. The small phonon energy (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples had been analyzed also by using optical absorption and emissi
