Recently, energy harvesting technologies based on the piezoelectric effect has attracted considerable interest. The perovskite nanoparticles are emerging as promising piezoelectric materials due to a high piezoelectric coefficient. In this study, organic-inorganic lead halide perovskite materials were employed to fabricate the piezoelectric NGs. A piezoelectric formamidinium lead halide perovskite(FAPbBr3) nanoparticles were synthesized with cubic perovskite structure. The FAPbBr3 nanoparticles were in detail characterized by field-emission transmission electron microscopy (FE-TEM), x-ray diffraction(XRD) measurement system. The piezoelectric NGs based on a composite of FAPbBr3 nanoparticles and polymer was prepared to evaluate the piezoelectric output voltage and current density. It could be achieved the comparable piezoelectric outputs, which was enough for applications in electronic devices, and smart sensors. |
