FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 single crystal samples undoped and doped which has a lower (five %) or higher (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of slim hexagonal plates. The small phonon Vitality (�?20 cm ⁻�?) was verified employing Raman spectroscopy. Samples were analyzed also by using optical absorption and emission
