PLE spectra showhigher intensities for sampleswith higher concentration and thicker layers. Excitation spectra of 20%wt. Eu-based PMMA filmobtainedwith SC diminish by a factor two respect the filmdeposited by TC technique. Also, the area under excitation band for TC films increases about 200% when two luminescent layers are deposited on top of the substrate. On the other hand, for SC films, fluorescent excitation intensity remains almost constant after adding an extra optically active layer. These results are in agreement with UV-VIS absorbance spectra.
