AI Article Synopsis
- Researchers used a slow exciton-to-dopant energy transfer process in Mn-doped perovskite to achieve ultrafast electron transfer to a 4-nitro phenol molecule.
- The electron shuttling process was measured to be approximately 140 femtoseconds, which is faster than the exciton scattering process.
- This method is three orders of magnitude quicker than the typical timescale for energy transfer from the exciton to the Mn dopants.
Article Abstract
Taking advantage of the slow exciton-to-dopant energy transfer process, we dissociated the exciton in Mn-doped perovskite ultrafast electron shuttling to a surface adsorbed 4-nitro phenol molecule. The observed ultrafast electron transfer process is competitive to the ultrafast exciton scattering process (∼140 fs) to the continuum states optical phonons, but three-orders faster than the exciton-to-Mn energy transfer timescale.
