They’re tiny inorganic semiconductor particles 10,000 times smaller than the diameter of a human hair. Yet, because of the unique combination of efficiency and narrow emission profiles, quantum dots are having an outsize impact on the consumer display market, posing a formidable rival to OLED technology. Unlike other down-converting materials, such as phosphors, quantum dots have a unique capacity to efficiently absorb high-energy blue light and re-emit that light at longer wavelengths, such as green and red. In quantum dot-enabled displays — marketed as QLED technology...Read full articleRelated content from Photonics MediaARTICLESQuantum Dot Microscope Can Measure Electric Surface Potentials of Single AtomsA new scanning quantum dot microscopy method can measure the electric potential of a sample at atomic accuracy.
