FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 single crystal samples undoped and doped with a small (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the form of slender hexagonal plates. The low phonon Electricity (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples ended up studied also by utilizing optical absorption and e
