FASCINATION ABOUT FE²�?ZNS CRYSTAL

KLuS two solitary crystal samples undoped and doped that has a very low (5 %) or significant (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the shape of slender hexagonal plates. The lower phonon energy (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples have been examined also through the use of optic
