Recrystallized PVDF was used as a host matrix for the PT3MA polymer and Zn2SiO4:Mn inorganic compound. The active layer was deposited on an indium-tin-oxide (ITO)-coated glass substrate by the drop casting technique. A spin-coating method was also used for morphological comparison purposes. The synthesized material as well as the device (aluminium electrodes/PVDF-PT3MA-Zn2SiO4:Mn/ITO/glass) was characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive X-ray spectroscopy (EDX), dark current-voltage (I-V) characteristic curves, absorbance and photoluminescence (PL) spectroscopy. The results show spherical-and irregular-shaped microparticles both dispersed on and within the PVDF matrix, which correspond to PT3MA and Zn2SiO4:Mn, respectively. The hybrid composite shows strong luminescence at approximate to 525 nm superimposed by a broadband between 600 and 800 nm, originating from the Zn2SiO4:Mn radiative transitions and from the recombination of photogenerated carriers at PT3MA. At room temperature, the device presented semiconductor behaviour typically observed for photodetectors and a DC electrical conductivity of approximate to 0.37 mu S cm(-1).
