CONSIDERATIONS TO KNOW ABOUT FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped with a lower (5 %) or large (38 %) focus of trivalent thulium or ytterbium ions were being synthesized in the form of thin hexagonal plates. The low phonon energy (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples were being analyzed also by using optical absorption and emission as w
