Fig. 13.6 The schematic
picture of the relationship
between wavelength and
bandgap in a visible light
Fig. 13.7 The figures of
selected molecular orbitals
(MOs) and corresponding
energy diagram at the local
minimum for SrTi 8 O 11 C
model
Figure 13.7 depicts the figures of selected MOs and corresponding energy diagram at the local minimum for SrTi 8 O 11 C model. The π -type Ti–C–Ti covalent
bonding in HOMO is the impurity level of carbon. HOMO-1 and LUMO are valence band and conduction band, respectively. It is concluded that visible light absorption energy corresponds to the orbital energy difference between impurity level
