DETAILS, FICTION AND FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped using a small (5 %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the shape of thin hexagonal plates. The low phonon Vitality (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples ended up studied also by making use of optical absorp
