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 when struck by an electron beam (cathode rays) in a cathode ray tube.

2 days ago· The photochemistry and photocytotoxicity of halfsandwich Osarene complexes have been investigated by experimental and theoretical methods. Osarene χurcumin complexes exhibit high potency and selective phototoxicity toward a range of cancer cell lines, especially toward cisplatinresistant cancer cell lines, but are relatively nontoxic to normal cells.

For example, the silicon chips in electronic devices (Figure 1.5), semiconductors and microchips of many sorts, and the LCD (liquid crystal display) screen on a smart phone are all crystalline. Light emitting diodes (LEDs) are commonplace in TV screens, light bulbs, and other devices. LEDs are crystalline.

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation.It is a form of luminescence.In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet

High carbon ferrochrome. See Charge chrome. HDG Hot Dip Galvanized. Refers to coil or sheet. Heap leaching A process for recovering metal, most commonly copper, from oxide or low grade ore or residues. Material is heaped up on an impermeable surface and sprayed with acid which picks up metal and is collected and sent for refining.
