General description

Trioctylphosphine serves as a phosphorus source and used in the synthesis of metal nanoparticles.

Application

Trioctylphosphine can be used for the conversion of metal nanocrystals, bulk powders, foils, wires, thin films to metal phosphides. It can also act as a solvent and stabilizer for synthesizing cadmium sulfide nanorods from cadmium acetate and sulfur.
