Solution

Dear Student,
The crystals of semi-conductor Gallium Arsenide Phosphide (GaAsP) depending on the relative mass percentage of Arsenic and Phosphorus can emit red light to infrared light.
In the context of your question, 35% As + 65% P is known to emit red light.
Chemical Formula-GaAs0.35P0.65
