Resumen

Photochromic polymers are materials with high potential for applications in optical devices. In this work we analyzed the polymeric matrix effect in convention and reconvertion efficiency of spiropyran trough Raman spectroscopy and fluorescence. Argon laser in 514 nm was used as excitation source. The results show the increase of fluorescence over the illumination time, one peak in λ=571 nm was present. The peak is associated with the molecular reconvertion from merocianine to spiropyran.
