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 ...

[Hydrogen Time] decided to make a green phosphorescent material, and has shared the process on Youtube, embedded below. The aim is to produce zinc sulfide crystals doped with copper impurities.

In OLEDs, light emission through the more energy-efficient phosphorescence is preferred over fluorescence, but phosphorescence happens more slowly, taking milliseconds or longer without the heavy ...
