Hydrothermal growth of nitrogen-doped ZnO crystals was performed in alkaline solutions with the addition of 1 N LiNO3 at Tdissoultion/Tgrowth=365°C/350°C, and in a 20% NH4OH solution at 490 °C/475 °C, respectively. An average nitrogen concentration of approximately 1018 atom/cm3 was incorporated in the crystals. X-ray diffraction showed that the crystals grown from the 1 M LiNO3 solution are of high quality, exhibiting high resistivity. The spontaneously nucleated crystals were obtained from the NH4OH solution; a weak peak at 3.236 eV and a peak at 3.332 eV of photoluminescence were found at 18 K from these crystals after annealing at 600 °C for 2 h. The emission peaks correspond to the nitrogen-associated donor–acceptor pair (DAP) and electron-acceptor emissions in ZnO:N prepared by other techniques reported in the literature.
