FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 one crystal samples undoped and doped by using a minimal (5 %) or substantial (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the shape of thin hexagonal plates. The reduced phonon energy (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples were studied also by utilizing optical absorption a
