FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 one crystal samples undoped and doped by using a low (5 %) or large (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of slim hexagonal plates. The lower phonon Electricity (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples have been examined also by utilizing optical absorptio
