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

KLuS 2 one crystal samples undoped and doped using a lower (5 %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions were synthesized in the form of thin hexagonal plates. The very low phonon Electricity (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples ended up analyzed also by making use of optical
