We show that the large observed optical bandgap is caused by parity-forbidden transitions, which are due to the centrosymmetry of double perovskite and the lowest conduction band being derived from the unoccupied In 5s orbitals. The large difference between the fundamental (independent of allowed/...
The good agreement of the experiment with the calculation suggests that the "parity-forbidden" combinations should be responsible for these anomalous optical transitions.doi:10.1016/0038-1098(94)90147-3X. ZhangSolid State Communications
Transition metal ion complexes are diverse and can be easily prepared, usually exhibiting a high IR light absorption capacity due to the d-d interband transitions12,13. In general, the transitions of electrons in d orbitals are parity-forbidden because of the same angular momentum quantum number...

Subsequently, Cu4(SO4)(OH)6nanosheets were synthesized and are found to undergo cascaded electron transfer processes based ond-dorbital transitions under infrared light irradiation. The obtained samples exhibit excellent activity for IR light-driven CO2reduction, with a production rate of 21.95 and ...

The temperature independence or dependence of the absorption bands, which are due to electric-dipole forbidden 4f5 4f5 transitions, is interpreted in terms of static or dynamic electron-lattice interaction, respectively.
