de-ionized water. The α-phase of In2Se3 is unchanged even after laser ablation. The In2Se3 nanocubes having a size of about 70 nm show the superior field emission behavior. The field electron emission maximum current density ~2.656 mA/cm2 at a field of 9.7 V/μm is achieved along with stable emission for 5 hours. We have also studied the electron decay analysis within the cubic structure using ultrafast transient absorption spectroscopy (UTAS) for a better understanding of carrier dynamics.
