In situ synthesis of photoluminescent films of PVC, doped with Ce3+ ion

摘要: Abstract In this paper we report on the in situ synthesis of photo luminescent and patterned polyvinyl chloride (PVC) films, doped with cerium chloride. The precursor doping agent is Tris(2-4 pentanedionate)cerium(III) 3H2O, Ce(acac)3, which absorbs UV visible light. PVC both photochemical source ion rigid matrix where CeCl3 particles are dispersed. films containing complex concentration range 0–3% w/w did not exhibit luminescence over 320 nm. After irradiation at 254 nm, pure exhibited emission a maximum about 420 nm, by excitation 300 nm, due to presence polyenes, likely formed photodehydrochlorination. complex, HCl photoproduct underwent substitution acac−, formation Hacac, detected XPS FTIR, respectively. Thus, these emissions 360 nm that polyenes was evidenced well 260 film appeared after an induction period function Ce(acac)3 percentage different for two emitting species, as resulted deconvolution band. using mask direct photopatterning. occurred exclusively from directly irradiated zones. Thus no reaction migration reactive species. FTIR analysis before sufficient obtain luminescence, evidence significant changes chemical structure polymer surface properties. method can be used provide without damaging side effect.
