WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS two solitary crystal samples undoped and doped by using a reduced (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the shape of slender hexagonal plates. The lower phonon Strength (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples had been examined also by using optical absorpti
