ABOUT FE²�?ZNS CRYSTAL

KLuS 2 solitary crystal samples undoped and doped by using a lower (five %) or large (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the form of thin hexagonal plates. The small phonon Electricity (�?20 cm ⁻�?) was verified utilizing Raman spectroscopy. Samples had been examined also by utilizing optical ab
