In this paper, we consider the Cauchy problem for the fractional Schrödinger equation i D t α u − ( − Δ )β 2u = 0 with 0 <  α  < 1, β  > 0. We establish the dispersive estimates by a carefully study of the Mittag‐Leffler functions and give some applications as well. In particular, we prove that the decay rates are sharp.
