Effects of noble metal particles and salts on the light stability of Safranin-O |
| 초록 |
How Safranin-O would be affected by noble metal (Au, Pt) nanoparticles was investigated. Effect of pH was also considered. In this study H2O2 were added to the Safranin-O aqueous solution to accelerate the experiments. We applied noble metal nanoparticles such as Au, Pt in colloidal condition HAuCl4 and H2PtCl6 as the noble metal salts. UV lamp (λ=254nm) was used as the light source. HCl and NaOH were used to control the pH of the solution. Optical properties of the noble metal and organic dye were investigated by UV-vis spectroscopy. The complexes between noble metals and the organic dye were confirmed by TEM. |
