Luminescent polymeric matrix composites are of great interest due to their wide range of applications, mainly in engineering, biotechnology and medicine1. There are biomedical approaches such as blood flow determination, medical imaging, flow cytometry among others; or applications in fluid engineering such as the determination of fluid velocity due to the simple velocity monitoring2. There are also technological applications for displays and emitting devices such as fluorescent tubes, lasers, projection television, flat panel screens among others2. The advantages of these composites are the combination of the transparency, good mechanical properties and easy processability of polymeric matrix with the optical properties of hydroxyapatite-barium titanate nanoparticles. The preparation of these composites was achieved by intimately suspending the nanoparticles in the vinyl acrylic polymers matrix. The properties of the different composites materials obtained, with different relative amounts of the aforementioned nanoparticles, were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Thermal Analysis (DSC and TGA) and UV-Vis Spectroscopy in order to evaluate the influence of the content of hydroxyapatite and barium titanate on the luminescent properties of these composite materials.
