EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS 2 solitary crystal samples undoped and doped that has a very low (five %) or high (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the form of skinny hexagonal plates. The small phonon Vitality (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples were being examined also by utilizing optical ab
