ABSTRACT:
The present invention provides a fluorescent material comprising a light-storing first phosphor that at least partially converts energy emitted by an excitation source to a first emission spectrum that is different from the energy, and a second phosphor that at least partially converts the first emission spectrum to a second emission spectrum that is different from the first emission spectrum; a lamp equipped with such a fluorescent material; a light-emitting device that produces a whitish afterglow, comprising such a fluorescent material for converting the emission by an LED chip; and a display unit comprising a display equipped with a plurality of such light-emitting devices.
