Paper Abstract

Recently a special attention is being paid to the studies of the proper and radiation-induced defects in the α-Al2O3 single crystals widely used in optoelectronics, laser technology and dosimetry. This is due to the fact that even in the nominally pure α-Al2O3 single crystal the structural defect concentration depends, to a considerable extent, on the initial burden quality, growing method and heat processing conditions. Depending on these factors, a series of crystal properties change essentially, especially the thermostimulated luminescence (TSL) and the X-ray luminescence (XL). The TSL intensity accumulated due to the isodose irradiation may serve the crystal defection criterion. In the present work, the integral TSL and the XL spectra of the nominally pure and doped α-Al2O3 single crystals produced by the GOI technique have been studied.
