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 ...

Transient absorption spectroscopy of rose bengal reveals triplet state dynamics, crucial for optimizing photosensitizers in ...

Phosphorescence is three times more efficient because it harnesses the other 75% of excited electrons too, but it requires the electron to flip its spin before it can come back down.

But they come with drawbacks—significantly higher cost, a shorter device lifetime and increased health and environmental hazards. In OLEDs, light emission through the more energy-efficient ...
