A REVIEW OF FE²�?ZNS CRYSTAL

KLuS two solitary crystal samples undoped and doped that has a minimal (5 %) or superior (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the form of slim hexagonal plates. The lower phonon energy (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples ended up researched also by utilizing optical absorpti
