Figure 5

UV–vis absorption spectra of (A) Zn-porphyrin dye. (B) a = CdS/ZnS and b = CdS/Mn-doped ZnS (on TiO2). (C) a = CdS/Mn-doped ZnS/Zn-porphyrin (on TiO2) and b = CdS/Mn-doped ZnS/Zn-porphyrin (on GO/N-doped TiO2). (D) a = CdS/ZnS, b = CdS/Mn-doped ZnS, and c = CdS/Mn-doped ZnS/Zn-porphyrin (on GO/N-doped TiO2).
