Dyes and Related Systems

Dyes and Related Systems - The small number of citations in this section certainly does not represent the extent of interest in dye photophysics. Much work of technological nature is not 

2 Dves and Related Systems - A major reason for an interest in dyes is the search for continuous improvement in the design of tuntable lasers. Amplified spontaneous emission is observed from 

CHjCl show that 0 0.5. Excited state absorption data in laser dyes at the XeCl wavelength have also been published.  

Absorption and fluorescence spectra of 7-aminocoumarin derivatives have been recorded and the photophysics of coumarin inclusion complexes with 0- and y-cyclodextrins investigated. Solvent effects on the photophysical behaviour of pyrrolocoumarin derivatives are similar to those on the psorolens . Vibronic exciton bands and the absorption spectra of Eosin Y dimers have been analysed theoretically and compared with experimental data. Picosecond spectroscopic studies have been made on the ionic photodissociation dynamics of malachite green leucocyanide . The lowest state produces ions within 0.1 to 0.5 ns whilst for higher states 6-13 ps are sufficient for the development of charge separation. The photophysics of crystal violet in a series of n- 

Fluorescence lifetimes and effects of aggregation of dyes on microcrystals of silver bromide give information directly relevant
