Studies of the Photoelectrochemistry of Organic Dyes Using Attenuated Total Reflection Techniques. Annual Progress Report, June 1, 1983-May 31, 1984

摘要

Employing two experimenal arrangements of internal reflection spectroscopy, work has been completed which define the energetic threshold for sensitized photocurrent and explore the photochemistry of J aggregate sensitization of semiconductor electrodes by cyanine dyes. The threshold measurements were made using a laser total internal reflection system (laser ATR); the aggregate experiments were done using internal reflection spectroscopy with white light (spectroelectrochemical IRS). A summary is made of the progress in measurements with H-band aggregates of cyanine dyes and triplet state studies with xanthene dyes. The direction of research during the remainder of the contract year is outlined. (ERA citation 09:006314)
