Beschreibung
Zusammenfassung:	In an embodiment, a radiation emitting device comprises a radiation emitting layer comprising a host material and a luminescent agent; and a radiation source that emits a source radiation; wherein the radiation emitting layer comprises an edge and two broad surfaces, wherein the edge has a height of d and the broad surfaces have a length L, wherein length L is greater than height d, and the ratio of L to d is greater than or equal to 10; and wherein the radiation source is coupled to the edge, wherein the source radiation is transmitted from the radiation source through the edge and excites the luminescent agent, whereafter the luminescent agent emits an emitted radiation, wherein at least a portion of the emitted radiation exits through at least one of the broad surfaces through an escape cone.
