WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS 2 one crystal samples undoped and doped with a small (five %) or superior (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the form of thin hexagonal plates. The minimal phonon Vitality (�?20 cm ⁻�?) was verified making use of Raman spectroscopy. Samples ended up studied also by making use of optical absorptio
