Abstract: Photoluminescence (PL) properties of synthesized Al-rich nanowhiskers with diameter 60±20 nm and bulk AIN single crystals were compared at the room temperature. It was found that PL spectra for AIN nanowhiskers were characterized by three components of the Gaussian shape with maximum energy 3.16, 2.90, and 2.55 eV and halfwidth 0.7, 0.4, and 0. 7 eV, respectively. It was shown that the same bands-3.2 and 2.6 eV-were observed in luminescence of the bulk and nanostructured samples. The registered emissions were attributed to electron-optical transitions between donor levels of the ON-VNcentera and acceptor states of the CN-centers and (ON-VAI)-complexes.. © 2014-STC "Institute for Single Crystals".
