EXAMINE THIS REPORT ON FE²�?ZNS CRYSTAL

KLuS 2 one crystal samples undoped and doped by using a very low (5 %) or high (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the shape of slim hexagonal plates. The lower phonon Electrical power (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples were examined also by making use of optical a
