Abstract

We summarized our recent studies on the photocarrier recombination dynamics of SrTiO₃ by means of time-resolved photoluminescence (PL) spectroscopy and transient absorption (TA) spectroscopy. Novel room-temperature blue PL was observed in strongly photoexcited SrTiO₃ and electron-doped SrTiO₃. We revealed that both PL and TA dynamics are determined by a simple carrier recombination model and nonradiative three-particle Auger process determines the carrier recombination dynamics under high-density photoexcitation. We discussed the temperature-dependent PL spectrum and dynamics of strongly photoexcited SrTiO₃.
