No. of bitstreams: 0 / Polímeros dopados com complexos de terras raras são materiais vantajosos na produção de filmes para várias aplicações no campo da luminescência. Neste estudo de polímeros luminescentes obtidos a partir de polímeros como o policarbonato (PC) e o poli(9-vinilcarbazol) (PVK), os filmes dopados com o complexo diaquatris (tenoiltrifluoroacetonato) de európio (III) [Eu(tta)3(H2O)2] foram preparados e suas propriedades térmicas e luminescentes no estado sólido relatadas. O comportamento térmico foi investigado por uso de calorimetria diferencial exploratória (DSC) e análise termogravimétrica (TGA). Devido à adição de complexo terras raras [Eu(tta)3(H2O)2] na matriz de PC e PVK, foram observadas alterações no comportamento térmico, relativo à transição vítrea e estabilidade térmica. As emissões finas características do íon Eu3+ decorrentes das transições 5DO → 7FJ (J = 0-4) indicaram a incorporação de íons de Eu3+ nos polímeros. Os filmes mostraram que a intensidade de emissão luminescente aumenta com o aumento da concentração de terras raras na matriz polimérica acompanhado por uma diminuição na estabilidade térmica. / Dissertacao (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP
