| description | A novel dual green and red-emitting photoluminescent polymer composite ZnAl<sub>2</sub>O<sub>4</sub>:Mn-bonded GO/polymethyl methacrylate (PMMA) was synthesized in a single-step reaction by surface-initiated atom transfer radical polymerization (SI-ATRP). The polymer chain was surface-initiated from the ZnAl<sub>2</sub>O<sub>4</sub>:Mn/GO, and the final products have a homogenous photoluminescent property from ZnAl<sub>2</sub>O<sub>4</sub>:Mn and better mechanical properties strengthened by graphene oxide (GO). The morphologies of ZnAl<sub>2</sub>O<sub>4</sub>:Mn/GO and the polymer composites were verified by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). X-ray diffraction analysis (XRD) revealed the two valence states of Mn (Mn<sup>2+</sup>, Mn<sup>4+</sup>) existing in the ZnAl<sub>2</sub>O<sub>4</sub> host lattice, while Fourier-transform infrared spectroscopy (FTIR) spectra proved the transference of the active group, C-Br, from the initiator to the monomer during the polymerization. Gel permeation chromatography (GPC) shows the narrow dispersity of polymer composites fabricated through SI-ATRP. The SEM and FTIR results show the successful ‘graft’ of the polymer chains from the surface of ZnAl<sub>2</sub>O<sub>4</sub>:Mn/GO. The dual green and red-emitting polymer composites were synthesized, confirmed by the photoluminescence (PL) and photoluminescence excitation (PLE) results. |
