gallium phosphide
Quick Summary
Gallium phosphide (GaP) is a compound semiconductor formed from gallium and phosphorus. When an electric current flows through GaP, a portion of the electrical energy is released as radiation, specifically visible green light. This phenomenon is known as electroluminescence.12
While GaP is not highly efficient in this process, it is used in light-emitting diodes (LEDs), primarily for indicator lamps and numeric displays. Other related semiconductor compounds can emit different colors of light.2
