Acesso em: 23 fev. 2015.0254-0584http://www.repositorio.ufop.br/handle/123456789/4672We report on the investigations about the modification of optical properties induced by X-rays onto film detectors of cadmium tungstate (CdWO4), poly[2-methoxy-5(20 -ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) and polystyrene (PS) This device takes advantage of reduction of spectral overlap between the radioluminescence (RL) of CdWO4 and the absorption of MEH-PPV as it is exposed to radiation, forming the basis of a new dosimeter that is capable of converting the orange-red radioluminescence of PS:MEH-PPV:CdWO4 into green. We propose an explanation of the optical processes occurring in MEHPPV:CdWO4 in terms of the radiation hardness of CdWO4 combined to the RL-induced degradation of MEH-PPV.en-USComposite materialsOptical materialsIrradiation effectsLuminescenceArtigo publicado em periodicoO periódico Materials Chemistry and Physics concede permissão para depósito do artigo no Repositório Institucional da UFOP.
