The electronic and optical properties of five Au16-derivatives have been calculated using the relativistic density-functional method.It is malyzed that two SiAu16-cages should be the most stable.The lowest-energy absorptions of five doped structures are all blue shifted relative to that of Au16-.The magnetic moments of five doped cages all are 1μB,as same as that of Au16-.Both the average linear static polarizability and the static linear polarizability anisotropies of the doped cages increase much when compared with those values of Aura-.
