Thermally stimulated luminescence (TSL) of x-ray-induced defects in R-Ba–Cu–O (R = Gd, Ho, and Eu) has been measured. In the interval 25–400°C, Ho- and Eu-doped samples exhibit similar TSL with peaks at 65, 135, and 185°C. The GdBa2Cu3Ox has, in addition to the three aforementioned peaks, a maximum at 310°C. All TSL peaks are attributed to recombination of F+s – and Fs center electrons with Vs-type holes, requiring typical thermal activation energies 0.5–1.0 eV. Spectral emission data support this conclusion. Irreversible quenching of TSL is found to occur in each sample. It is postulated that adsorbed oxygen molecules interact with radiation-induced F+s and Fs centers to produce O2 and O2−2 molecular ions, respectively, thereby reducing the surface oxygen vacancy concentration and quenching the luminescence. In addition to activation energies, other TSL parameters are extracted from the data. It is suggested that surface TSL in these oxide superconductors is independent of rare-earth dopant.

21Note that the subscript designating surface states (i.e., F,+, Fs, and Vs) was not used in Ref. 11. We suggest hereafter that a distinction between bulk centers (F+,F, and V) and surface centers (Fs+, F,, and Vs) be clearly adhered to by use of a subscript, although theoretical work [R. Sharma and A. M. Stoneham, J. Chem. Soc. Faraday Trans. II72, 913 (1976) ] suggests that optical transition energies of surface and bulk centers are quite close.
