5 SIMPLE STATEMENTS ABOUT FE²�?ZNS CRYSTAL EXPLAINED

KLuS two solitary crystal samples undoped and doped using a low (5 %) or significant (38 %) concentration of trivalent thulium or ytterbium ions were being synthesized in the form of thin hexagonal plates. The very low phonon energy (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples had been analyzed also by using optical absorp
