HELPING THE OTHERS REALIZE THE ADVANTAGES OF FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped by using a low (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the shape of slim hexagonal plates. The very low phonon Strength (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples have been studied also through the use of optical absor
