Controlled synthesis of novel rod-like Cu 1.81 S nanostructures and field emission properties
Source abstract
Abstract
Abstract Three flower-like and one rod-shape cubic Cu 2 S nanostructures were successfully synthesized from a facile hydrothermal method employing CuCl 2 ·2H 2 O and thiourea as Cu and S source with different volume ratio of ethanol and distilled water, respectively. Hexadecyl trimethyl ammonium Bromide (CTAB) plays an important role in forming the nanorod. After thermal annealing treatment, tetragonal Cu 1.81 S nanoflower and nanorod were obtained for the first time. Field emission (FE) properties of these nanostructures were investigated for the first time. The results indicated that the tetragonal Cu 1.81 S nanorods had excellent field emission performance with turn-on field of ∼2.2 V μm −1 , threshold field of ∼5.1 V μm −1 and enhancement factor of 1532. It showed that the tetragonal Cu 1.81 S nanostructures were competitive material in field emission applications.
