FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 one crystal samples undoped and doped using a minimal (5 %) or high (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of slim hexagonal plates. The very low phonon Power (�?20 cm ⁻�?) was verified using Raman spectroscopy. Samples were examined also by making use of optical absorption and emission togeth
