摘要：

The thermoluminescence (TL) of heated amorphous ZrO2, doped by Ti, Th, U, Nb, Dy, excited by 253.7 nm or X‐radiation is investigated. Six main peaks are observed at 100, 135, 190, 245, 285, and 385 K and their activation energies determined by four methods. It is shown that most traps obey Curie's model, and that the tetragonal form, which coexists with the monoclinic form, is related to the 245 K peak. The analysis of various TL emission spectra indicates that the emission centres are localized and are connected with Ti3+ surrounded by six oxygens. A centre model is discussed in terms of configuration coordinate curves. Copyright © 1978 WILEY‐VCH Verlag GmbH & Co. KGaA
