Product Overview
We are leading manufacturer of Rare Earth Fluorescent Powder For Lamps in Guangzhou, Guangdong, China. Fluorescent powder, also called phosphor, most generally, is a substance that exhibits the phenomenon of luminescence. Somewhat confusingly, this includes both phosphorescent materials, which show a slow decay in brightness (> 1 ms), and fluorescent materials, where the emission decay takes place over tens of nanoseconds. Phosphorescent materials are known for their use in radar screens and glow-in-the-dark toys, whereas fluorescent materials are common in cathode ray tube (CRT) and plasma video display screens, sensors, and white LEDs. Fluorescent powder or Phosphors are often transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT(cathode ray tube) displays and fluorescent lights. CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number.Phosphorus, the chemical element named for its light-emitting behavior, emits light due tochemiluminescence, not phosphorescence.
