We evaluate the rare decays Bs →γe+e- in the standard model, considering the off-shell effect of quarks in Bs meson as well as some contributions neglected in previous works. It is found that the quarks off-shell are large.With the predicted branching ratios at order of 10-8, it is expected that the radiative dileptonic decays will be detected in the LHC-b experiments.
