Influence of oxygen-content on the cathodoluminescence of YBa_2Cu_3O_(7-x)

The influence of oxygen content of YBa_2Cu_3O_(7-x) ceramic samples on the cathodoluminescence emission has been studied in the scanning electron microscope. No luminescent band has been related to the presence of native oxygen vacancies in untreated samples. On the other hand vacancies are involved...

Sumario:The influence of oxygen content of YBa_2Cu_3O_(7-x) ceramic samples on the cathodoluminescence emission has been studied in the scanning electron microscope. No luminescent band has been related to the presence of native oxygen vacancies in untreated samples. On the other hand vacancies are involved in luminescent centers formed after some treatments as electron irradiation.
