Abstract

In this Letter, we report oxygen vacancy dominant strong visible photoluminescence (PL) from multiferroic BiFeO₃(BFO) nanotubes (NTs) prepared by sol-gel template method. Abundant oxygen vacancies present in BFO NTs provide alternate paths for the photo-induced carrier generation and recombination thus affecting the PL and photoabsorption characteristics. This study not only assists in understanding the optoelectronic characteristics of BFO NTs at nanoscale but also suggests BFO nanostructures as potential candidates for future photonic and sensing applications.
