FE²�?ZNS CRYSTAL NO FURTHER A MYSTERY

KLuS two one crystal samples undoped and doped which has a small (5 %) or higher (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the form of skinny hexagonal plates. The small phonon Power (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples were researched also by using optical absorption and emission
