FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 solitary crystal samples undoped and doped which has a low (five %) or substantial (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the form of thin hexagonal plates. The very low phonon Vitality (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples were examined also by utilizing optical absorption a
