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.

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

Luminescent solar concentrators (LSCs) harvest sunlight over large areas and concentrate this energy onto photovoltaics or for other uses by transporting photons through macroscopic waveguides. Although attractive for lowering solar energy costs, LSCs remain severely limited by luminophore reabsorption losses.
