5 ESSENTIAL ELEMENTS FOR FE²�?ZNS CRYSTAL

KLuS 2 one crystal samples undoped and doped having a small (five %) or significant (38 %) concentration of trivalent thulium or ytterbium ions were synthesized in the form of slender hexagonal plates. The lower phonon Electricity (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples were analyzed also by using optical absorptio
