In this work, we synthesized well-grown cadmium sulfoselenide (CdSSe) microflowers on gold-coated silicon substrate using a simple and low-cost chemical bath deposition technique. The deposited CdSSe film was annealed in a furnace for 30 min at [Formula: see text]C. Subsequently, the annealed CdSSe film was further characterized using structural, morphological and field-emission analyses. The CdSSe microflowers show photosensitive field-emission behavior. In the photosensitive field emission, the emission current rises by nearly 2–3 times of its primary preset current value of [Formula: see text]A.
