FACTS ABOUT FE²�?ZNS CRYSTAL REVEALED

KLuS two one crystal samples undoped and doped which has a low (5 %) or significant (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of thin hexagonal plates. The minimal phonon Strength (�?20 cm ⁻�?) was verified utilizing Raman spectroscopy. Samples had been researched also through the use of opt
