The O atom of maleic anhydride is in coordination with metal ions on the surface of the phosphors. |
First, the quality of the phosphors available in the early days was not that great, and the dots would start to fade out before the entire screen could be painted. |
In a cathode-ray tube display, a scanning electron beam causes phosphors to glow at selected spots. |
Other particles containing yttria and some lanthanides are phosphors that be processed to form light-emitting devices. |
The inside of the tubes are coated with phosphors that give off visible light when struck by ultraviolet energy. |
These are systems that incorporate a phosphor wheel with green or yellow phosphors in combination with laser sources. |
