Abstract

In the present paper the photoemission intensity versus excitation exposure time of host/guest photoluminescent polymer blend has been investigated. The polymer blend was composed by poly(methyl methacrylate) (PMMA) as a host, and Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV) as a guest. The photoluminescent blend was characterized by optical absorbance and steady-state photoluminescence spectroscopy. The PMMA/MEH-PPV blend film presented high homogeneity and high photoemission intensity. Moreover, the PMMA/MEH-PPV blend film photodegradation in function of sample exposure time to the blue-light excitation curve presented long biexponential time decay. These results suggest that the PMMA/MEH-PPV blend film could be used as a long time exposure blue-light dosimeter.
