American Elements is a manufacturer and supplier specializing in producing quantum dots from several semiconductor materials, including Cadmium Telluride (CdTe), Cadmium Selenide/Zinc Sulfide (CdSe/ZnS), Lead Selenide (PbSe) and Zinc Cadmium Selenide/Zinc Sulfide (ZnCdSe/ZnS) nanoparticles with well-defined peak emission frequencies between approximately 470 to 730 nm wavelengths.
Quantum Dots have the unique ability to emit light representing the entire rainbow of colors from the same elemental material based solely on the size of the particles of that material being excited. Prior to quantum dots, light emitting semiconductors, such as light emitting diodes (LED), could not emit white light. AE Quantum Dots with particle size distributions less than 500 nanometers (nm) produce LED emissions in the blue range which may allow for the commercial use of solid state semiconductors to generate luminescent light. The resulting revolution could be compared to Thomas Edison's original invention of the light bulb; the technology which LED lighting would potentially render obsolete. – less–ZoomInfo
