Copper oxide nanoparticles from nanoComposix have a polyvinylpyrrolidone (PVP) surface and are available in a standard size of 50 nm diameters. The particles have very good size and shape uniformity, and are provided in water at 1 mg/mL.

Cuprous oxide (Cu2O) is a p-type semiconductor with interesting excitonic features and a bulk band gap of 2.17 eV. Recently, several studies have demonstrated the potential of Cu2O for gas sensing, photodegradation of dye molecules, CO oxidation, photo-activated water splitting, as anti-bacterial material for sterilization and as electrode material for lithium ion batteries.

The optical properties of Cu2O nanoparticles are highly size-dependent, and exhibit contributions from the semiconductor absorption and light scattering from the particles.

The size, capping agent, and dispersion media of cuprous oxide (Cu2O) nanoparticles can be tuned for your application. NanoComposix has successfully manufactured monodisperse cuprous oxide (Cu2O) nanoparticles with sizes or diameters tunable from 30 nm up to 240 nm, and dried, redispersible samples are available in some instances.
