Gallium nitride (GaN) samples implanted with magnesium and fluorine ions are investigated by photoluminescence (PL) measurements. In low‐temperature PL, green luminescence (GL) due to nitrogen vacancies (V N) is observed in magnesium‐ion‐implanted GaN, but the GL disappears when fluorine ions are implanted at an appropriate concentration.
