Properties of Y-Shaped PFO-DBT Nanotubes

Figure 5

Optical absorption spectra of Y-shaped PFO-DBT nanotubes. (a) Absorption spectra of unannealed PFO-DBT solution (immersed for 1 hour) and annealed PFO-DBT solution (immersed for 1 hour). (b) Absorption spectra of annealed PFO-DBT solution of different aging time (1, 24, and 72 hours).
