FE²�?ZNS CRYSTAL SECRETS

KLuS two solitary crystal samples undoped and doped with a low (five %) or large (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the shape of slender hexagonal plates. The small phonon Strength (�?20 cm ⁻�?) was verified making use of Raman spectroscopy. Samples had been studied also by utilizing optical ab
