Abstract (German)

In dieser Arbeit werden ternäre und quaternäre Natriumchalkogenometallate untersucht. Gegenstand von strukturellen und spektroskopischen Untersuchungen sind Verbindungen der pseudo-binären Phasendiagramme Na₂Q-Pn₂Q₃ (Pn = As, Sb, Bi; Q = S, Se, Te) und Na₂Q-Pn₂Q₅ (Pn = P, As, Sb; Q = S, Se) sowie die Verbindungen Na₂TeQ₃ (Q = S, Se). Die Strukturen werden mittels Röntgenbeugung an Einkristallen ...

Translation of the abstract (English)

In this work compounds of the systems Na₂Q-Pn₂Q₃ (Pn = As, Sb, Bi; Q = S, Se, Te), Na₂Q-Pn₂Q₅ (Pn = P, As, Sb; Q = S, Se), and Na₂TeQ₃ (Q = S, Se) were characterized. The crystal structures were determined by X-ray diffraction on powders or single crystals. The interactions between Pn and Q atoms were investigated by Raman-spectroscopy. The optical band gaps of NaPnQ₂, Na₃PnQ₃, and Na₂TeQ₃ were ...
