We report on time-integrated and time-resolved photoluminescence (PL) measurements in 80 mm thick GaN layers grown by hydride vapor phase epitaxy on sapphire substrates. The PL spectra are dominated by free exciton transitions and by three well-resolved emissions assigned to the neutral-donor-bound
