  We study the pair production of charged scalar particles from the
five-dimensional near extremal Reissner- Nordstr\"om-Anti de Sitter (RN-AdS5)
black hole. The pair production rate and the absorption cross section ratio in
the full spacetime are obtained and are shown to have proportional relation
with their counterparts in the near horizon region. In addition, the
holographic descriptions of the pair production both in the IR CFT in the near
horizon region and the UV CFT at the asymptotic spatial boundary of the RN-AdS5
black hole are analyzed in the AdS2/CFT1and AdS5/CFT4correspondences,
respectively. This work gives a complete description of scalar pair production
in the near extremal RN-AdS5black hole.
