Title
Transient absorption measurement of organic crystals with femtosecond-laser scanning microscopes
Abstract

Two types of femtosecond-laser scanning transient absorption microscopes have been developed as tools for observing ultrafast exciton dynamics in organic solids, which have recently received much attention for their roles as organic photofunctional devices, such as solar cells and light-emitting diodes. One microscope is a multiphoton excitation transient absorption microscope, and the other is an apertured probe transient absorption microscope. Their performance was evaluated by measuring transient absorption spectra, kinetics and images of perylene crystals.
