PL spectra of a thick PS layer as a function of the pressure during HWA. The HWA was done at 260 °C for 3 h.
The external QE values of PL emission and the corresponding PL peak wavelengths of the PS samples represented in Fig. 1 as a function of the HWA pressure. Data at zero pressure represents an as-anodized sample with no HWA treatment.
ESR signals of PS samples (1–4) treated by HWA (260 °C, 3 h) under different pressures. The result of an as-anodized PS sample (denoted by A) is also shown. All PS samples are thick self-supporting layers. Microwave frequency was 9.878 GHz.
The PL peak intensities for PS layers shown in Fig. 3 as a function of the spin density obtained from ESR data. The sample notations are the same as those shown in Fig. 3. The corresponding factors obtained from the respective ESR data are also plotted.
