Abstract:
Photoluminescence (PL) spectra of anion-defective alumina single crystals and ultradisperse ceramics were measured under excitation in the vacuum ultraviolet (VUV) region. Emission bands in the experimental PL spectrum were identified using a developed technique to reconstruct spectra of luminescent dielectrics. A correspondence was found between the calculated and experimental PL spectra of alpha-Al2O3 single crystal. The PL spectrum of ultradisperse anion-defective alumina ceramic was calculated taking into account luminescence centers created by intrinsic and impurity defects. Bands in the experimental spectrum were identified based on it.
