Remote Phosphor Offers Alternative to White LEDs DigiKey
WebDepending on the type of phosphor, the intensity of the emitted light will decrease faster. The more efficient the phosphor, the slower its light intensity decays after excitation. Our time-resolved cameras and camera attachments use P43 phosphor. The high luminous efficiency of this phosphor increases the light levels at the output of the ... A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy. The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow … See more The scintillation process in inorganic materials is due to the electronic band structure found in the crystals. An incoming particle can excite an electron from the valence band to either the conduction band or the See more Many phosphors tend to lose efficiency gradually by several mechanisms.
