WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS 2 one crystal samples undoped and doped with a minimal (5 %) or significant (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the form of thin hexagonal plates. The minimal phonon energy (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples were being examined also by utilizing optical absorption and
