Glow-in-the-dark. How does it work?
Glow-in-the-dark. How does it work? In this video I show a bunch of phosphorescent samples and explain the difference between fluorescence and phosphorescence.
Link to my video about fluorescence: Fantastic Fluorescence!
If you are interested in more you should search for chromium-activated zinc gallogermanate (Zn3Ga2Ge2O10 : 0.5%Cr3+). They glow invisble in near infrared but can glow for up to two weeks in the dark!
Hopefully the scientists will invent something similar that glow in the visible range for so long. I would definitely pay well for a phosphor that could glow on my watch for such a long time.
