THE DEFINITIVE GUIDE TO FE²�?ZNS CRYSTAL

KLuS 2 solitary crystal samples undoped and doped which has a minimal (5 %) or significant (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the form of thin hexagonal plates. The low phonon Vitality (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples have been analyzed also by making use of opti
