AT2017gfo is the first kilonova (KN) that could be extensively monitored in time both photometrically and spectroscopically. However, kilonova emission have also been found contributing to the optical counterparts of several short Gamma-ray Bursts. Here I present our attempt to search for the fingerprints of kilonova emissions in the optical/NIR light curves of 39 short GRBs with known redshift and how our results allow us to constrain separately the range of luminosity of the blue and red components of AT2017gfo-like kilonovae in short GRBs. With these results at hand, I show up to which red shift a KN can be followed up by some of the current and future observatories.
