In traditional cathode-ray sets, those primary colors are created using phosphors, while liquid crystal displays rely on colored filters.

The lamps are still fluorescent type, using special phosphors that create a spectrum in the UVA and UVB range.

They use more luminous phosphors on the screen at the expense of restricting the color spectrum.

This aspect is comparable to fluorescent lamps and to the neon signs that use colored phosphors.

They are available in a wider range of screen sizes than CRT and plasma displays, and since they do not use phosphors, they do not suffer image burn-in.

Alternative light sources use phosphors or combinations of mono-chromatic LEDs (red, blue, green) to produce "white" light, giving significantly irregular spectral distributions which can result in color casts in photography and differences of color matching when compared to incandescent light or daylight.

LaO is also used in X-ray imaging intensifying screens, phosphors as well as dielectric and conductive ceramics.

With the drive off there was no ready ultraviolet for the engineers to step down into the optical region, so they had gone back to using phosphors strung along the zero-g axis.

Radioluminescence uses the radioactive decay of tritium to light the sign, while phosphorescence uses light-emitting phosphors to glow in the dark.
