TOP FE²�?ZNS CRYSTAL SECRETS

KLuS two single crystal samples undoped and doped having a very low (5 %) or high (38 %) focus of trivalent thulium or ytterbium ions were being synthesized in the form of slim hexagonal plates. The low phonon energy (�?20 cm ⁻�?) was confirmed making use of Raman spectroscopy. Samples have been studied also by using optical absorption and em
