How is a Phosphor Made? Phosphors are usually made using a stable inert host material (typically oxides, nitrides, silicates, sulfides, or selenides) doped in small quantities with activators (such as metal or rare earth ions), which create non-homogeneities or impurities in the crystal struct...
Phosphorus is created in supernovae, exploding massive stars at the end of their lives, but new research suggests that typical supernovae may not provide the conditions needed for forging the element. Life as we know it may be rarer than we think This is why astronomer Jane Greaves from Ca...
using a screen saver can provide two main benefits: preventing burn-in and providing entertainment when you’re not actively using your computer. burn-in happens when the same image stays on an lcd monitor too long and creates visual patterns due to “phosphor exhaustion”, this can cause ...

they emit colors that react with a phosphor screen that lights up to enhance the effect. Each cell of gas is referred to as apixel, and can display either a red, blue, or green light. Together mixtures of thousands of these pixel displays are used to make up television images. The adva...

LED phosphor, in a narrow sense, is a kind of Photoluminescent materials can absorb the energy of violet and blue light from gallium nitride or other LED chip, and transform it into visible light. Phosphors are made of solid luminescent materials, which can absorb blue light (450-460 nm) ...
