2.1 Emitting radioluminescence

EL coldluminescence

Objects outside of a radiation-thermal radiation.

NOTE. The duration of this radiation to light than the oscillation period.

2.2 Fluorescence

After excitation stop, duration less than 10-8s luminous.

Example.

Steam, gas or liquid at room temperature, emitting a typical fluorescence.

Note. Sometimes not to emit light is defined as the duration of the fluorescence, but the spontaneous emission of molecules called fluorescence.

2.3 Phosphorescence

After excitation stop, duration greater than 10-8s luminous.

Example.

Emitting heavy metal activated alkaline earth metal light-emitting substance is typical of phosphorescence.

Note. Sometimes the recombination luminescence of crystals called phosphorescence. But now fluorescence and phosphorescence are not critical distinction.

2.4 Photoluminescence

UV, visible or infrared radiation generated by excitation light-emitting material to emit light.

Example.

Fluorescent light.

2.5 EL electroluminescence

Cause luminescence in the solid field or current role.

Note. The current common electroluminescent material, there are three forms. junction, film and powder, wherein the powder electroluminescent another DC and AC points.

2.6 AC electroluminescent ACelectroluminescence

Alternating electric field caused by the light emission.

NOTE. It is excited by an alternating electric field, even if the conduction current through the small, still give light.
