THE BEST SIDE OF FE²�?ZNS CRYSTAL

KLuS two single crystal samples undoped and doped using a small (5 %) or high (38 %) concentration of trivalent thulium or ytterbium ions were synthesized in the shape of thin hexagonal plates. The small phonon Electricity (�?20 cm ⁻�?) was verified making use of Raman spectroscopy. Samples ended up studied also through the use of optical abs
