Abstract: We present for the first time the X-ray luminosity function of short gamma-ray bursts (sGRBs) estimated from 22 Fermi sGRBs. We find that the cumulative distribution of X-ray emission at rest frame 200 s is well described by a broken power law function, which is ϕ (L X , 0) ∝ L X , 0 − 0.20 ± 0.04 for dim bursts and ϕ (L X , 0) ∝ L X , 0 − 1.05 ± 0.11 for bright bursts, with the break luminosity is 2.57 × 10 46 erg s − 1 , where the cosmological evolution of luminosity is taken into account. We also find that the early X-ray luminosity of sGRBs is correlated with the isotropic energy/luminosity of prompt emission. These results are need to confirm with large observed data of sGRBs.
