FACTS ABOUT FE²�?ZNS CRYSTAL REVEALED

KLuS two single crystal samples undoped and doped which has a small (five %) or higher (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of thin hexagonal plates. The very low phonon Electrical power (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples have been studied also by utilizing optical ab
