碩士 === 國立中山大學 === 光電工程研究所 === 95 === We have successfully implemented the time-resolved technique at frequency domain on a laser scanning microscope. The method is implemented via interfacing a lock-in amplifier with the laser scanning microscope and is used to investigate organic photonic devices (OPD). The available modalities include electroluminescence and optical beam induced current. In this way, temporal response of a device can be investigated at high spatial resolution. Despite of its now limited role in flat panel display, OPD presents as a versatile material with numerous potentials, with solar power panel as the most noted one recently. The investigation conducted enables us to better understand the fundamental dynamics of carriers unique to OPDs.
