Dynamic aspects of the dye-sensitized photoconductivity of semiconductors. Technical progress report
Technical Report
·
OSTI ID:5748924
Our efforts have been directed along three separate lines of investigation of dyes adsorbed on semiconductor and insulator surfaces: First, direct fluorescene lifetime measurements aimed at exploring injection and the processes which compete with it. Second, fluorescence quantum yield measurements as a function of surface coverage, designed to further examine the processes competing with injection, energy transfer quenching in particular. Third, construction of a fast transient absorption spectrophotometer to probe the oxidized dye population, designed to examine the competition between recombination and escape.
