Fig. 8. Singlet oxygen emission spectra for ZnTPP in water (blue line) and ZnTPP/D-g-PAAan (green line) and ZnTPP/D-g-PAAan/AuNPs (red line) water-based solutions. Water-based solutions of Au NPs (black line) and D-g-PAAan/AuNPs (magenta line) without ZnTPP show no oxygen emission; excitation: 553 nm; concentrations: ZnTPP, 0.01 g L−1; D-g-PAAan, 0.080 g L−1; Au, 0.079 g L−1.
