General description

Trioctylphosphine serves as a phosphorus source and used in the synthesis of metal nanoparticles.[1]

Application

Trioctylphosphine can be used for the conversion of metal nanocrystals, bulk powders, foils, wires, thin films to metal phosphides.[2] It can also act as a solvent and stabilizer for synthesizing cadmium sulfide nanorods from cadmium acetate and sulfur.[3]
