The revival structures for the X_m exceptional orthogonal polynomials of theScarf I potential endowed with position-dependent effective mass is studied inthe context of the generalized Gazeau-Klauder coherent states. It is shown thatin the case of the constant mass, the deduced coherent states mimic full andfractional revivals phenomena. However in the case of position-dependenteffective mass, although full revivals take place during their time evolution,there is no fractional revivals as defined in the common sense. Theseproperties are illustrated numerically by means of some specific profile massfunctions, with and without singularities. We have also observed a closeconnection between the coherence time {\tau}_coh^m? and the mass parameter ?.
