- W2034603048 abstract "We report unusual photoluminescence (PL) behaviors in highly photoexcited ${mathrm{SrTiO}}_{3}$ crystals at low temperatures. The PL spectrum and dynamics show abrupt changes below 150 K in both nondoped and electron-doped ${mathrm{SrTiO}}_{3}$ samples. We clarified that the PL dynamics in both nondoped and electron-doped ${mathrm{SrTiO}}_{3}$ is well described by the same simple model involving single-carrier trapping, radiative bimolecular recombination, and nonradiative Auger recombination. The unusual temperature dependence of PL dynamics is caused by the crossover from Auger recombination at high temperatures to single-carrier trapping at low temperatures. We discuss the temperature-dependent PL dynamics in conjunction with the high carrier mobility of ${mathrm{SrTiO}}_{3}$ at low temperatures." @default.
