Anwendungen & Verwendung
Verwenden
Trioctylphosphine oxide (TOPO) is most commonly used as the solvent due to its high boiling point and chemical stability, and its ability to prevent particle aggregation via coordination to the NP surface. trioctylphosphine oxide is a frequently used surfactant, starts to decompose at around 425℃.
