Large-area nanoscale farmland-like surfaces of one-dimensional NbO2 nanorods with multi-growth directions: studies on the purple-blue photoluminescence and low-field electron emissions

Abstract

We synthesized a scenic morphological form of a large-area NbO2 nanoscale farmland using the hot-filament metal-oxide vapor deposition technique (HFMOVD). The nanoscale farmland is comprised of one-dimensional (1D) NbO2 nanorods arranged in various domains, which grow in multi-directions. Each domain contains ∼620 nanorods per square micrometer and has its own growth direction. The 1D NbO2 nanorods are found to have purple-blue photoluminescence (PL) emissions at room-temperature as well as very low turn-on and threshold fields for field emission (FE). The PL and FE results indicate that the 1D NbO2 nanorods are brilliant light and electron emitters.
