FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS 2 one crystal samples undoped and doped which has a very low (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the shape of slim hexagonal plates. The small phonon Power (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples ended up studied also through the use of optical absorption and
