The peak absorbance of Xerogel films doped with R6G goes up with an increase of the spinning
speed, as well as the ratio of the peak absorbance of the monomer to that of the dimer. The absorption spectra at the lowest speed were almost without structure, while at higher speeds they became more structured. Moreover, its absorption band at 516 nm, related to aggregation, decreases after drying.On the contrary, the absorption band related to the monomer, increases after drying.
