Bismuth sulfide (Bi2S3) nanoflowers with unit size of about 5 μm and "petals" on the scale of 50~100 nm were investigated for field emission (FE) properties. Current density of the Bi 2 S 3 nanoflowers versus applied electric field and the Fowler-Nordheim (F-N) plot, as well as long term stability of FE performance were experimentally studied. Results show that the Bi 2 S 3 nanoflowers have good FE properties a turn-on field of 1.18 V∙μm -1 before the long-term stability test, which implies that the nanoflowers have good potential for FE applications. Also, the long-term stability results show stable FE current density over 60 hours under an electric field of 2 V∙μm -1 . The FE of the device was tested again; the FE performance was similar to that before the long-term test.
