Tb-doped ZnO:PDMS based flexible nanogenerator with enhanced piezoelectric output performance by optimizing nanofiller concentration
Source abstract
Abstract
Abstract Zinc oxide (ZnO) is one of the most prospective material for optoelectronic, piezoelectric, spintronic and gas sensing applications. Doping rare-earth elements in ZnO leads to significant enhancement in its electrical properties. Herein, pure and Tb-doped ZnO nanoparticles were synthesized via chemical co-precipitation method and their structural, morphological and electrical properties were systematically studied. As a result of Tb-doping, hexagonal shaped ZnO nanorods converted to taper-like nanoparticles. Tb–ZnO nanoparticles exhibited high Curie temperature (Tc ~ 225 °C) and enhanced dielectric properties as compared to pure ZnO nanoparticles. Electrical conduction studies revealed a significant reduction in the leakage current as a result of Tb-doping. Piezoelectric nanogenerators based on synthesized nanoparticles were fabricated and piezoelectric output voltage of the Tb-doped ZnO based nanogenerator was measured to be remarkably enhanced (by up to ~ 4 times) compared to pure ZnO based nanogenerator. These results indicate Tb–ZnO:PDMS composite films on flexible substrates could be promising candidate for energy harvesting application.
