In the last years, considerable advances have been made in the development and optimization
of polymeric materials, in sense to improve their physical properties. One of most important
properties of the polymers is the capacity to behave as excellent insulating electric even for
high frequency voltages. However, in the last years has been increasing the interest of
research in the polymeric composites. The mixture of the different polymeric materials helped
to eliminate or reduce the limitations of the pure polymers such as the fragility of the
polystyrene (PS) and the low flexibility of the
polyvinyl chloride (PVC). The development and

Figure 1: Fluorescence spectra of the
photonics. Therefore, this work shows a study of
Eu3+ doped PVC
the photoluminescent optical properties of the
polyvinyl chloride (PVC) polymers doped with several concentrations of Eu3+ prepared
following casting method [1]. Measurements of the UV-Vis transmittance were done to
confirm the optical quality of the PVC. The IR transmittance measurements were also used to
verify the incorporation of the Eu3+ in the polymeric matrix. Although, the Figure 1 presents
the fluorescence measurements for the PVC and PVC Eu3+ doped samples in different
concentrations. The result shows a broad band emission in the whole visible region. We
conclude that the Eu3+ incorporation in the polymeric matrix improves the PVC emission
inducing an increase in the fluorescence spectra. The results are used to evaluate the reliability
of these materials as photonic materials.
