Photodegradation of MB and amplitude enhancement of electric field. (a) The photodegradation of MB solution by S1 to S4 and reference sample TiO2 under UV light irradiation (inset) and the corresponding plots of <a onClick="popup('http://www.nanoscalereslett.com/content/8/1/73/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/8/1/73/mathml/M2">View MathML</a> versus the irradiation time, showing the linear fitting results. (b) Amplitude enhancement of the electric field inside a TiO2 layer is simulated by the FDTD method.
