| Term (EN) | spontaneous emission |
|---|
| Definition (EN) | Electromagnetic radiation emitted when the internal energy of a quantum mechanical system drops from an excited level to a lower level without regard to the simultaneous presence of similar radiation.
Note. — Examples of spontaneous emission include radiation from an LED, and radiation from an injection laser below the lasing threshold. |

| Term (SR) | spontana emisija |
|---|
| Definition (SR) | Elektromagnetno zračenje koje se emituje kada unutrašnja energija kvantno-mehaničkog sistema opadne iz stanja pobude na niži nivo, bez obzira na istovremenu prisutnost sličnog zračenja.
Napomena — Primjeri spontane emisije uključuju zračenje iz LED, i zračenje iz injekcionih lasera ispod praga pojačanja. |
