Abstract

A simple solution chemistry route is employed for the synthesis of V2O5 nanoflakes and V2O5/MWCNTs nanocomposite. An attempt for enhanced field emission properties is carried out by nanocomposite formation of V2O5/MWCNTs. The as-synthesized product is characterized further by SEM, XRD, TEM, etc. The field emission characteristics are measured at the base pressure of 1 × 10−8 mbar. The turn-on field defined as the field required to draw an emission current density of10 µA/cm2 is found to be 1.75, 1.3 and 0.66 V/µm for V2O5nanoflakes, MWCNTs and V2O5/MWCNTs nanocomposite, respectively. Herein, more than 2.5-fold reduction in turn-on field for V2O5/MWCNTs nanocomposite is reported for the first time. The observed value of lowturn-on field ofV2O5/MWCNTs nanocomposite is found to be quite remarkable than the values reported for other V2O5 nanostructures. In addition, high current density of 977 µA/cm2 is recorded at an applied field of 1.15 V/µm. Further, the emission current stability is recorded for preset of 10 µA emission current for the duration of 2 h. A detail discussion on correlation between morphology of the emitter and obtained field emission results is presented in paper.

Graphical abstract

Here in, more than 2.5-fold reduction in turn-on field for V2O5/MWCNTs nanocomposite is reported. The observed value of low turn-on field of V2O5/MWCNTs nanocomposite is found to be quite superior than the values reported for V2O5 nanostructures. Exploration of field emission properties of present emitter is important for scientific and technological advancement.
