The absence of _______________ in LEDs limits the internal quantum efficiency.
A)proper semiconductor
B)adequate power supply
C)optical amplification through stimulated emission
D)optical amplification through spontaneous emission

Question

Quizplus · Accepted Answer

LEDs (Light Emitting Diodes) operate based on spontaneous emission rather than stimulated emission, which is a characteristic of lasers. The absence of optical amplification through stimulated emission limits the internal quantum efficiency of LEDs.
