摘要：

The three-dimensional hierarchical SrS/Bi2S3 heterostructures were synthesized by a template-free single-step hydrothermal method. The structural and morphological studies revealed the formation of a single crystalline orthorhombic heterostructure with rod-like morphologies possessing a high aspect ratio. The field emission properties of SrS/Bi2S3 nanorods were investigated. J-E and the Fowler-Nordheim (F-N) plot, as well as long-term field emission (FE) stability, were studied. SrS/Bi2S3 nanoflowers have enhanced the FE properties more than the virgin Bi2S3. The observed values of the re-producible turn-on field for SrS/Bi2S3 defined to draw an emission current density of ca. 1 mu A/cm(2) were found to be ca. 2.50 V/mu m, and of the threshold field to draw a current density of ca. 10 mu A/cm(2) were found to be ca. 3.00 V/mu m (without visible light illumination). A maximum emission current density of ca. 527 mu A/cm(2) was drawn without light and a current density of ca. 1078 mu A/cm(2) with light, which is higher than that of pristine Bi2S3.
