Researchers control multiple wavelengths of light from a single source  December 10, 2020 In carbon dots multi-wavelength emission can be stimulated under a single excitation source, enabling the simple and robust generation of white light from a single particle. Carbon dots also exhibit a concentration-dependent photoluminescence; however, this has not been fully understood. To understand this phenomenon and fully utilize the capabilities of carbon dots, researchers in South Korea posited and demonstrated that the dual-color-emissiveness is due to the interparticle distances between each carbon dot. They examined how the relative light intensity of the red and blue colors changed when varying the interparticle distances. They found that as the […]
