FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS two one crystal samples undoped and doped which has a low (5 %) or substantial (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the form of skinny hexagonal plates. The very low phonon Electrical power (�?20 cm ⁻�?) was verified using Raman spectroscopy. Samples were researched also by using optical absorption
