THE 5-SECOND TRICK FOR FE²�?ZNS CRYSTAL

KLuS 2 one crystal samples undoped and doped by using a low (5 %) or higher (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the shape of slender hexagonal plates. The minimal phonon energy (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples were examined also by using optical absorption and em
