Spoiler alert: almond butter isn’t phosphorescent. But powdered milk is, at least to the limit of detection of this homebrew phosphorescence detector. Why spend a bunch of time and money on such ...

Phosphorescence, which occurs when a molecule transitions from a high-energy state to a low-energy state, often competes with non-radiative processes where the molecule loses energy as heat.

We’ve seen “persistence of phosphorescence” clocks before, but not as good looking and legible as this one. We like the approach, and we can’t help but think of other uses for glow-in-the ...

Not only have brands managed to squeeze incremental bits of extra performance (including extra brightness) out of standard, ...

Researchers at Tohoku University, the Tokyo University of Science and the Indian Institute of Technology Madras have successfully enhanced the phosphorescence quantum yield of silver (Ag ...
