Abstract:
We present an instructional design strategy to tune the optical absorption ability of organic-inorganic hybrids by managing the internal iodide state. Three bismuth-based hybrids with different internal iodide states were synthesized and display tunable bandgaps from 1.91 eV to 1.87 eV and finally to 1.59 eV.

IR Absorption Frequency: Hybridization
Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that...
