| Popis: | Erbium and ytterbium codoped LaF 3 nanoparticles coated with organic ligands and Poly (phthalazine ether sulfone ketone) (PPESK) nanocomposites were prepared in this paper. The morphologies of nanoparticles were characterized by TEM. The thermal and photoluminescence properties of the PPESK nanocomposites were investigated by DSC, TGA and photoluminescence spectra. It was found that the nanoparticles with particle size of 20 nm can be homogeneously dispersed in PPESK-in-chloroform solutions, which allowed the transparent film to be facilely prepared. The photoluminescence spectra of PPESK nanocomposites film and solution in chloroform both reveal the typical features of the transition of Er 3+ from 4 I 13/2 to 4 I 15/2 at 1530 nm. By adding nanoparticles to PPESK matrix, the T g of PPESK has little change and the initial degradation temperature decreases. |
