News Fluorescent Dyes

  • Inverted Fluorescence

    Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to the s more

  • Luminous Molecules

    Many people know the effect from discos when “black light” makes clothes or writing boards glow. The reason for this are so-called fluorescent dyes. They send back part of the light they are exposed to in a slightly different way and thus glow. Particularly large fluorescent molecules are often inte more

  • Smart Fluorescent Dyes

    Controlling the excited electronic states in luminescent systems remains a challenge in the development of fluorescent and phosphorescent dyes. Now, scientists in Japan have developed a unique organic fluorophore that changes its emission color without loss of efficiency when externally stimulated. more

A Glow-in-the-Dark Battery Technology

University at Buffalo scientists have identified a fluorescent dye called BODIPY as an ideal material for storing energy in large-scale rechargeable batteries. Such batteries could one day be used to stockpile energy harvested from green sources such as solar and wind. more
