THE SMART TRICK OF FE²�?ZNS CRYSTAL THAT NO ONE IS DISCUSSING

KLuS 2 solitary crystal samples undoped and doped which has a minimal (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the shape of slender hexagonal plates. The very low phonon Vitality (�?20 cm ⁻�?) was verified making use of Raman spectroscopy. Samples have been examined also by utilizing optica
