FACTS ABOUT FE²�?ZNS CRYSTAL REVEALED

KLuS two single crystal samples undoped and doped using a minimal (5 %) or large (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of skinny hexagonal plates. The minimal phonon Electricity (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples were being analyzed also by making use of optical absorption
