The temporal changes of the optical transmission, in photosensitive solutio
ns containing chlorophyll (Chl) were monitored. Specifically, Chl-a solutio
ns in ethanol sensitive to visible and UV spectrum were used to quantify an
d analyze the surface film photodeposition and volume photobleaching phenom
ena occurring in these systems. SEM microscopy revealed the microstructure
of the deposited films. (C) 2000 Elsevier Science S.A. All rights reserved.
