Impact of Surface Trap States on Electron and Energy Transfer in CdSe Quantum Dots Studied by Femtosecond Transient Absorption Spectroscopy [PDF]
Nanomaterials, 2023 The presence of surface trap states (STSs) is one of the key factors to affect the electronic and optical properties of quantum dots (QDs), however, the exact mechanism of how STSs influence QDs remains unclear. Herein, we demonstrated the impact of STSs

Effect of reabsorption of fluorescence on transient absorption measurements
Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2019 Elimination of fluorescence reabsorption effects is necessary to obtain reliable kinetic data in fluorescence spectroscopy. This effect must also be considered in transient absorption spectroscopy. We devised two methods to achieve this goal. The first was use of a thin optical cell (
