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 ...

A huge decayed Tree bad succumbed to the gale, and suddenly at its uprooting and fracture the ground all around it blazed up in luminous phosphorescent light; the trees and shrubhery all about ...

Credit for the first practical phosphorescent lamp belongs to Tesla—phosphorescent substances are slower to emit light than fluorescent ones, and they continue to glow for some time after the ...

True. Check out any modern “paper” (i.e., polymer note) currency with non-trivial security features (basically, anything but US notes). Some fluorophores glow only with 365 nm light, some with ...

Adding phosphorescent light to the wild activity of the food chain really helps bring it to life and make it more real. Sign Up for the A.M. Report Keep up with Noozhawk's daily news coverage ...

From anti-counterfeiting inks to bioimaging agents, phosphorescent materials that glow after light exposure are critical for security and sensing applications. However, most current systems rely ...
