EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS 2 solitary crystal samples undoped and doped using a minimal (5 %) or high (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the form of skinny hexagonal plates. The minimal phonon energy (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples had been analyzed also through the use of optical abs
