WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS 2 solitary crystal samples undoped and doped which has a minimal (five %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of thin hexagonal plates. The low phonon Strength (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples were being examined also by making use
