WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS 2 one crystal samples undoped and doped using a reduced (5 %) or large (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the shape of slender hexagonal plates. The minimal phonon Strength (�?20 cm ⁻�?) was verified employing Raman spectroscopy. Samples were being analyzed also by making use of optical absorption
