The X-ray afterglow of many gamma-ray bursts (GRBs) exhibits a plateau phase before the normal power-law decay stage, which may be related to continued activities of the central engine. Tang et al. collected 174 such GRBs and confirmed the so-called L-T-E correlation which involves three key parameters, i.e., the isotropic γ-ray energy E_γ,iso of the prompt phase, the end time T_a of the plateau phase, and the corresponding X-ray luminosity L_X. In this study, the L-T-E correlation is confirmed and updated as ${L}_{{\rm{X}}}\propto {T}_{{\rm{a}}}^{-0.99}{E}_{\gamma ,\mathrm{iso}}^{0.86}$ with a large sample consisting of 210 plateau GRBs with known redshifts. The tight correlation is then applied to derive the pseudo-redshift of other 130 plateau GRBs whose redshifts are not directly measured. Statistical analysis is also carried out on this pseudo-redshift sample.
