ABOUT FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped using a low (five %) or significant (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of slim hexagonal plates. The small phonon Vitality (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples ended up studied also by making use of optical absorption
