Your key has phosphors on it.
These phosphors can even cause cancer.
Depending on the original LED's color, various color phosphors are used.
Or white phosphors with pink pigment or dye over top.
Depending on the color of the original LED, phosphors in different colors may be used.
Phosphors The substances that CRT monitors use to emit light.
How would I get phosphors on my key?
Remote phosphors provide more diffuse light, which is desirable for many applications.
So then she starts talking about phosphors and the key having chemicals on it, right?
Your monitor, forexample, creates color by emitting light through red, green, and blue phosphors.
Depending on the colour of the original LED, phosphors of different colour can be used.
Harmful phosphors have been found in the instant noodle package cups from every famous brand sold in China's supermarkets.
Depending on the color of the original LED, phosphors of different colors can be employed.
However, using different phosphors fluorescent materials it also became possible to instead produce green and red light through fluorescence.
This method involves coating LEDs of onecolor(mostly blue LEDs made of InGaN) with phosphors of different colors to form white light;
Multicolor LEDs without phosphors cannot provide good color rendering because each LED is a narrowband source.
The mercury vapor emission spectrum is dominated by a short-wave UV line at254 nm(which provides most of the energy to the phosphors), accompanied by visible light emission at 436 nm(blue), 546 nm(green) and 579 nm(yellow-orange).
However multicolor LEDs without phosphors can never provide good quality lighting because each LED is a narrow band source(see graph).
Electroluminescence is the result of radiative recombination of electrons& holes in a material, usually a semiconductor. The excited electrons release their energy as photons- light. Prior to recombination, electrons and holes may be separated either by doping the material to form a p-n junction(in semiconductor electroluminescent devices such as light-emitting diodes) or through excitation by impact of high-energyelectrons accelerated by a strong electric field(as with the phosphors in electroluminescent displays).
PLASMA: Unlike LCDs, plasma displays use phosphors excited with noble gases to display pixels and give them color.
Since LCD screens do not use phosphors, they suffer image burn-in when a static image is displayed on a screen for a long time, e.g. the table frame for an airline flight schedule on an indoor sign.
The best color rendition CFL andLEDs use a mix of phosphors, resulting in less efficiency but better quality of light.
Improvements since then have largely been better phosphors, longer life, and more consistent internal discharge, and easier-to-use shapes(such as compact fluorescent lamps).
Interpreter: This one is called Instant Noodles.(Laughter) LB: Since August 2012,harmful phosphors have been found in the instant noodle package cups from every famous brand sold in China's supermarkets.
Another method used to produceexperimental white light LEDs used no phosphors at all and was based on homoepitaxiallygrown zinc selenide(ZnSe) on a ZnSe substrate that simultaneously emitted blue light from its active region and yellow light from the substrate.
PLASMA: Unlike LCDs, plasma displays use phosphors excited noble gases to display pixels and provide them with color.
