✨🪨A fluorescent & phosphorescent rock!🪨✨ Fluorescence is seen with UV illumination, while phosphorescence is visible in the dark. Fluorescence is fast (ps-ns), while phosphorescence is slow (ms-min). #FluorescenceFriday #SciArt #SciComm #RealTimeChem #Chemistry

🔹🔷Fluorite Fluorescence!🔷🔹 George Stokes coined "fluorescence" in 1852 after fluorite, which glows blue under UV light. Fluorite is CaF2. Fluorescence is usually caused by yttrium, europium, or samarium impurities. #FluorescenceFriday #RealTimeChem #SciComm
