I have calculated the band gap of my visible-active photocatalyst using tauc's method. The calculated band gap was 2.86. According to the following equation, I have calculated the wavelength which is corresponding to that band gap:
Wavelength(in nm)=1240.8/Energy(in eV) = 433.57 nm
What does this WAVELENGTH mean?
I'm sure that it is not the maximum wavelength for absorption because my absorption vs. wavelength plot shows absorption until the end of visible region (800 nm). Furthermore, I'm sure that it is not highest wavelength at which absorption occurs because my absorption vs. wavelength plot has maximum @ 480-503 nm.
