Processing Iron Oxide Nanoparticle-Loaded Composite Carbon Fiber and the Photosensitivity Characterization

“…From the data fitting formula of Equation (3), the approximate value for the time constant τ is 416.7 s. It is evident that both the formula as shown by Equation (3) and the data in Figure 5b reveal a slow decaying property, which is exactly required for some applications including photonic sensing, bio-imaging, and cell-labelling as discussed earlier in [31].…”

“…Figure 5b illustrates the general trend of the potential change with time, t, in the ON interval for the composite containing iron nanoparticles in the carbon fibers under the visible light illumination. We can adopt the following formula to fit the trend of the time-dependent open circuit potential, E, as used earlier in [31]: From the results illustrated in Figure 4, we can see that the difference between the maximum and minimum voltage values is about 0.4 V. The highest voltage was observed when the florescence light source was switched to the ON state. If the fluorescent light source was ON, the voltage was instantly generated by the specimen.…”
