In a modern, scientific sense, the phenomena can usually be classified by the three different mechanisms that produce the light, [further explanation needed] and the typical timescales during which those mechanisms emit light. Whereas fluorescent materials stop emitting light within nanoseconds (billionths of a second) after the excitation ...
