WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS 2 solitary crystal samples undoped and doped with a very low (five %) or substantial (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the form of skinny hexagonal plates. The very low phonon energy (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples had been studied also by utilizing optical absor
