Remón is acknowledged.The effect of oxygen loss on the luminescence of YBa_2Cu_3O_(7-x) has been investigated by cathodoluminescence (CL) in the scanning electron microscope (SEM) and by Raman microprobe measurements. The results herein indicate that a CL band at 530 nm is related to oxygen loss rather than to impurity phases such as Y_2O_3 formed in the material by electron irradiation in the SEM.engjournal articlehttp://dx.doi.org/10.1063/1.355147http://scitation.aip.orgopen access538.9High-Tc-SuperconductorsRaman-ScatteringFilmsSpectroscopyMicroscopeFísica de materiales
