Time-resolved Spectroscopic Study on Photocarrier Generation Process in Layered Organic Photoreceptors
Abstract:We applied highly sensitive time-resolved absorption spectroscopy to the study on the electronic structures and dynamics of ionic transient species in layered organic photoreceptors. Long-lived transient absorptions assignable to the cationic species of charge transport materials (CTMs) were observed in the visible, near- and mid-infrared wavelength regions. The bands in infrared region can be ascribed to the delocalized holes within some CTM molecules. We discuss the nature of ionic transients generated in photoreceptors.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
