Do Particles Interact Electronically? -Proof of Interparticle Charge-transfer Excitation between Adjoined Anatase and Rutile Particles

Here, we report experimental evidence of interparticle spatial overlapping of orbitals to result in interparticle charge-transfer excitation (ICTE) at an anatase-rutile interface which is expected to be applicable to clarify the relative band position of metal-oxides and mixture homogeneity of mixture samples measured by reversed double-beam photoacoustic spectroscopy.

Automated summary

Experimental evidence shows that interparticle spatial overlapping of orbitals leads to interparticle charge-transfer excitation at an anatase-rutile interface, which can help clarify the relative band position of metal-oxides and the mixture homogeneity of mixture samples.
