CONSIDERATIONS TO KNOW ABOUT FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped using a lower (five %) or higher (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of slender hexagonal plates. The very low phonon energy (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples were analyzed also by utilizing optical absorption and emissi
