摘要：
Thermoluminescence of YBa2Cu3O7−δ (YBCO) samples as a function of quenching temperature (with increase in oxygen deficiency) is investigated. In unquenched samples three glow peaks around 90, 145, and 195 K are observed. With increasing quenching temperature the overall intensity of the 145 K peak increases. The centres responsible for this peak are attributed to the oxygen vacancies. The activation parameter is calculated and presently calculated activation parameter data are compared with the data reported earlier by other researchers.
