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.

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 ...

These nanodots are capable of emitting multicolored, ultra-long, room-temperature phosphorescence ranging from blue to green. These materials exhibit potential applications in anti-counterfeiting ...
