THE BASIC PRINCIPLES OF FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped having a lower (5 %) or significant (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of slender hexagonal plates. The very low phonon Vitality (�?20 cm ⁻�?) was verified using Raman spectroscopy. Samples ended up examined also by using optical absorption and emiss
