Emittierende

Emittierende is the present participle form of the German verb emittieren and functions as an attributive adjective. It describes entities that emit energy, particles or radiation. The expression is common in scientific and technical contexts and is used with nouns such as Quelle (source), Schicht (layer), or Elektronen (electrons). The form adapts to gender and number, for example emittierende Schicht (feminine, singular) or emittierender Körper (masculine, singular).

In physics, emitting processes refer to the release of energy in the form of photons or other quanta. An emittierende Quelle is any source that outputs radiation or particles, with characteristics such as emission rate, spectrum and angular distribution being of interest. Key concepts include spontaneous emission, stimulated emission and thermal emission, all of which describe how a system can produce radiation.

In technology and engineering, emittierende components are central to light sources and detectors. In LEDs, OLEDs and laser diodes, the emittierende Schicht (the active layer) is where charge carriers recombine or transitions occur to produce light. This layer determines efficiency, color and brightness. The term also appears in imaging, spectroscopy and accelerator contexts, where emitting elements generate secondary radiation or particles for measurement or application.

Language usage notes: emittierende is used as a present participle adjective and agrees with the noun it modifies. Related terms include Emission (emission) and emittierende Quellen as a general descriptor for emitting entities.
