WebBlack, White, and Gray: Nothing, All, or Some. When no electrons strike the phosphors of a computer screen the phosphors emit no light and the screen appears black. On a white section of a screen all three phosphors are excited and produce light with about the same relative intensities as in sunlight so the light appears white. WebVibration will only cease at absolute zero (approximately -273 oC). Efficient phosphors hold their ions very tightly, preventing the loss of energy through “non-radiative transitions”. …
