HELPING THE OTHERS REALIZE THE ADVANTAGES OF FE²�?ZNS CRYSTAL

KLuS 2 single crystal samples undoped and doped which has a lower (five %) or superior (38 %) focus of trivalent thulium or ytterbium ions had been synthesized in the shape of slim hexagonal plates. The low phonon energy (�?20 cm ⁻�?) was verified applying Raman spectroscopy. Samples were being studied also by using optical absorption and emi
