THE 5-SECOND TRICK FOR FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped that has a small (5 %) or higher (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of slender hexagonal plates. The lower phonon Power (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples ended up researched also by using optical absorpt
