THE BASIC PRINCIPLES OF FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped having a very low (5 %) or significant (38 %) concentration of trivalent thulium or ytterbium ions had been synthesized in the form of skinny hexagonal plates. The lower phonon Electricity (�?20 cm ⁻�?) was confirmed utilizing Raman spectroscopy. Samples were researched also by using optical abso
