High Excitation Intensity Opens a New Trapping Channel in Organic-Inorganic Hybrid Perovskite Nanoparticles
Zheng, Kaibo; Zidek, Karel; Abdellah, Mohamed; Chen, JunSheng; Chabera, Pavel; Zhang, Wei; Al-Marri, Mohammed J.; Pullerits, Tonu... more authors ... less authors ( American Chemical Society , 2016 , Article)We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. We confirmed the sub-band gap ... -
Size-And Wavelength-Dependent Two-Photon Absorption Cross-Section of CsPbBr3 Perovskite Quantum Dots
Chen, Junsheng; Zidek, Karel; Chabera, Pavel; Liu, Dongzhou; Cheng, Pengfei; Nuuttila, Lauri; Al-Marri, Mohammed J.; Lehtivuori, Heli; Messing, Maria E.; Han, Keli; Zheng, Kaibo; Pullerits, Tonu... more authors ... less authors ( American Chemical Society , 2017 , Article)All-inorganic colloidal perovskite quantum dots (QDs) based on cesium, lead, and halide have recently emerged as promising light emitting materials. CsPbBr3 QDs have also been demonstrated as stable two-photon-pumped lasing ...
