Luminescence enhancement of ZnO-poly(methylmethacrylate) nanocomposite films by incorporation of crystalline BaTiO3 nanoparticles

Photoluminescence, thermal and surface properties of triarylimidazole-containing polyimide nanocomposite films

“…In addition, the permittivity of nano-Si 3 N 4 is higher than that of nano-SiO 2 , so the result is similar with that reported in the literature. 46 Thus, the type and content of doped nanoparticles play an important role in the photoluminescence properties of PI nanocomposite films.…”

“… 45 The introduction of nanoparticles will weaken the ordered stacking state of PI molecular chains, enlarge the distance between molecular chains, and reduce the interaction between the chains. According to the literature, 46 the barium titanate nanoparticles with high permittivities could increase the fluorescence intensity of the ZnO–polymethylmethacrylate nanocomposite film. Hence, it is expected that the ceramics nanoparticles have a positive impact on the optical property of photoluminescent PI film.…”
