Facile Synthesis of Photofunctional Nanolayer Coatings on Titanium Substrates

Figure 4

Absorption (a) and phosphorescence spectra (b) of the pure HP in ethanol and the HP-coated Ti substrate. The absorption spectrum of the HP-coated Ti substrate was obtained by applying the Kubelka-Munk function to the diffuse reflectance spectrum. The excitation wavelength was 408 nm for the emission spectrum.
