We report that the blue photoluminescence (PL) dynamics are dependent on both the photogenerated and the chemically doped carrier densities in SrTiO(3). We found that the PL decay dynamics are well explained using a simple model that includes nonradiative single-carrier trapping, radiative bimolecular recombination, and nonradiative Auger recombination processes. In highly photoexcited SrTiO(3) and heavily electron-doped SrTiO(3), the rapid Auger recombination of the polarons determines the PL properties.
