FACTS ABOUT FE²�?ZNS CRYSTAL REVEALED

KLuS two one crystal samples undoped and doped having a small (5 %) or large (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the form of slender hexagonal plates. The small phonon Electricity (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples were being examined also by utilizing optical absor
