Specific Features of Spectrally Resolved Thermoluminescence in UV-Irradiated Aluminum Nitride Microcrystals
Published in Optics and Spectroscopy
AbstractThe mechanisms of photo- and thermoluminescence processes in cation-deficient submicron AlN crystals after UV excitation are studied. The observed emission spectra represent a superposition of bands peaking at 3.0 and 2.5 eV. These spectral features are related to electronic transitions with participation of ON impurity centers and oxygen–v...
