In this work, it was studied the performance of YVO4:Eu3+ nanoparticles (NPs) synthesized and functionalized and the development of polymeric nanocomposites (PNCs) YVO4:Eu3+/PMMA for Fiber-optic Dosimetry. The NPs were synthesized by a combustion method. Results of XRD and Fluorescence Spectroscopy confirmed the identity of YVO4:Eu3+. SEM images revealed that ≈55% of NPs had a particle size between 50-200 nm. Two functionalization strategies were evaluated: i) using 3-(trimethoxysilyl)pro...
In this work, it was studied the performance of YVO4:Eu3+ nanoparticles (NPs) synthesized and functionalized and the development of polymeric nanocomposites (PNCs) YVO4:Eu3+/PMMA for Fiber-optic Dosimetry. The NPs were synthesized by a combustion method. Results of XRD and Fluorescence Spectroscopy confirmed the identity of YVO4:Eu3+. SEM images revealed that ≈55% of NPs had a particle size between 50-200 nm. Two functionalization strategies were evaluated: i) using 3-(trimethoxysilyl)propyl methacrylate as coupling agent and ii) covering with SiO2 and subsequent treatment with oleic acid. In both cases, FTIR and DLS analysis confirmed the presence of these compounds.In addition, PNCs were synthesized. The polymerization kinetics of methyl methacrylate and the development of films based on these PNCs were studied. Preliminary results indicate that PNCs with YVO4:Eu3+ NPs functionalized with the silane coupling agent have a better performance for this technological application.Keywords: YVO4:Eu3+, polymethyl methacrylate, luminescence, nanocomposites, Fiber-optic Dosimetry
