中文Luminous afterglow time and its measurement
An important characteristic of luminescent materials is its luminous duration. According to the duration of luminescence, luminescence can be divided into fluorescence and phosphorescence. The gap between excitation and emission of fluorescence is very short, about < 10-* s. As soon as the light source leaves, the fluorescence will disappear. Phosphorescence will emit light for a long time after the excitation source leaves. Afterglow can also be used to indicate the duration of light emission. Afterglow is defined as:...
