Europium-doped La 2 O 3 nanocrystalline powders with sizes in the range of 50–200nm have been obtained by the modified sol–gel Pechini method. These nanocrystals have been deagglomerated using sonication for 3h and have been dispersed into a semiconductor P3HT polymeric matrix. We studied and analysed the spectroscopic properties of the trivalent europium in the hexagonal La 2...
An efficient method based in template wetting is applied for fabrication of ordered Poly(9,9-dioctylfluorene) (PFO) nanopillars with β-phase morphology. In this process, nanoporous alumina obtained by anodization process is used as template. PFO nanostructures are prepared under ambient conditions via infiltration of the polymeric solution into the pores of the alumina with an average pore diameter...
