Product Description	Product Describtion: 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. Product Application： Tri-n-octylphosphine is used for coating zinc sulfide shells on cadmium-selenium quantum dot core by successive ionic layer adsorption and reaction method. It acts as a precursor to trioctylphosphine oxide. Further, it is used as a solvent for cadmium and selenium precursors. It also serves as a common reagent in the chemical synthesis of nanoparticles. It acts as a precursor to trioctylphosphine oxide.
