NOT KNOWN DETAILS ABOUT FE²�?ZNS CRYSTAL

KLuS two solitary crystal samples undoped and doped using a lower (five %) or significant (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the form of slender hexagonal plates. The minimal phonon energy (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples were analyzed also through the use of optical absor
