strong synergistic effect of the (110) and (100) facets of the SrTiO3 perovskite micro/nanocrystal: decreasing the binding energy of exciton and superb photooxidation capability for Co2+

We have obtained self-trapping excitons (STEs) with an ultra-low binding energy by regulating the synergistic effect of (100) and (110) facets in the SrTiO 3 micro-nano crystal, which processed super photo-oxidation performance for Co 2+ .
