Rhodamine 6G- (R6G) doped thin sol-gel films were cast on glass microscope slides and characterized with the use of steady-state and time-resolved fluorescence spectroscopy. The fluorescence intensity, photodegradation under laser illumination, and excited-state decay kinetics were all investigated as a function of dopant concentration. The excited-state decay kinetics of highly doped films show clear evidence of R6G aggregation. Photodegradation under laser illumination is very interesting and is discussed in detail.

Deposition Conditions

ABSTRACTBackscattering spectrometry has been used to determine the density of TiO2 sol-gel films. The density of the as-deposited films relative to that of anatase varies slightly with respect to deposition conditions and is approximately 0.5. Annealing at temperatures as high as 750°C increases the relative density to 0.7 with concomitant decreases in the O:Ti ratio and H content but it does not result in complete densification. Film densities are consistently higher for films annealed under dynamic vacuum compared to those in air.
