Line emission above the direct interband threshold is observed at 77\ifmmode^\circ\else\textdegree\fi{}K in $\mathrm{Ga}{\mathrm{As}}_{1\ensuremath{-}x}{\mathrm{P}}_{x}:\mathrm{N}$ for $x=0.19 \mathrm{and} 0.21$. This emission is identified with a sharp resonance state of the N isoelectronic trap. This state owes its existence both to the attractive short-range nature of the trap potential and to the details of the energy-band structure of $\mathrm{Ga}{\mathrm{As}}_{1\ensuremath{-}x}{\mathrm{P}}_{x}$.
