Cd Free Quantum Dots
NanoOptical Materials offers Cd Free Quaternary Quantum Dots (Q-QDs) composed of CuInZnS cores surrounded by a shell of ZnS. Quantum Dots (QDs) are nearly ideal luminescent materials because of their high brightness, strong optical absorbance over a wide excitation wavelength range, photostability and narrow emission spectra. These nanomaterials are finding a wide range of applications. However the toxicity of Cd based QDs limits their use in a number of applications such as in vivo diagnostics, product packaging, and consumer products.
High quality Cd Free CuInZnS/ZnS core/shell QDs are available over the wavelength range of 540 nm to 720 nm, starting at $145. Both organic soluble and water soluble forms may be purchased. Follow the links below to obtain more information and to order.
