Fe²�?ZnS Crystal Fundamentals Explained
KLuS two single crystal samples undoped and doped using a low (five %) or higher (38 %) concentration of trivalent thulium or ytterbium ions ended up synthesized in the form of skinny hexagonal plates. The small phonon energy (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples were researched also by using optical absorption and
