Figure 5
The position of surface plasmon resonance vs the thickness of TiO 2 cover. For MIFs prepared using annealing in hydrogen at 150°C, 250°C, and 300°C. The absorption spectra of initial MIFs are presented in Figure 2b. Inset: the SPR shift vs the cover thickness for all prepared samples; stars denote the samples annealed at 150°C, the smallest silver islands.
