5 SIMPLE TECHNIQUES FOR FE²�?ZNS CRYSTAL

KLuS 2 solitary crystal samples undoped and doped using a minimal (five %) or large (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the form of skinny hexagonal plates. The reduced phonon Vitality (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples were examined also by making use of optical absor
