Facile Synthesis of Photofunctional Nanolayer Coatings on Titanium Substrates

Figure 6

Reaction-time-dependent UV-vis spectra of DPBF in the presence of the HP-coated Ti substrate in THF solution with white light. The inset presents the decay curves of DPBF absorption OD at 415 nm as a function of irradiation duration: (a) DPBF only under light irradiation, (b) DPBF with the HP-coated Ti substrate in the dark condition, and (c) DPBF with the HP-coated Ti substrate under the light condition.
