Summary:

In the work reported here was obtained a lead-free NaNbO3 / PVDF composite, starting from photoluminescent ceramics particles with 1D morphology obtained by microwave-assisted hydrothermal method. Photoluminescence spectrum of the NaNbO3 particles shown emission around 445 nm, and P-E hysteresis loop of composite shown remanent polarization of 1.5 µC/cm2. The combination of optical properties showed by the NaNbO3 particles with the electrical and flexible properties presented by composite can make it possible material applied in flexible devices whit piezophotonics or piezo-phototronics properties.
