Electron-beam irradiation of the i region of an i-n structure based on zinc-doped gallium nitride is observed to increase the intensity of the cathodoluminescence band with maximum at $\hbar \omega=2,87$ eV. The emission intensity increases by 1.5-2 orders of magnitude in comparison with the intensity at the initial period of the irradiation. Irradiation beyond the broad maximum caused the intensity to decrease. The experiments were carried out with electron-beam energy 20 keV, current density up to 200 A/cm$^2$, and sample temperature 300°K.
