All-inorganic colloidal perovskite quantum dots (QDs) based on cesium, lead, and halide have recently emerged as promising light emitting materials. CsPbBr3 QDs also been demonstrated stable two-photon-pumped lasing medium. However, the reported two photon absorption (TPA) cross sections for these differ by an order of magnitude. Here we present in-depth study TPA properties with mean size ranging from 4.6 to 11.4 nm. By using femtosecond transient (TA) spectroscopy found that section is...
Organometal halide perovskites have attracted tremendous attention for optoelectronic applications. Charge carrier trapping is one of the dominant processes often deteriorating performance devices. Here, we investigate details trap behavior in colloidal nanoparticles (NPs) CH3NH3PbBr3 with mean size 8 nm and corresponding bulk crystals (BCs). We use excitation intensity dependence photoluminescence (PL) dynamics together comprehensive simulation charge trap-state dynamics. In at very low...
Photo-generated charge carrier dynamics in Ruddlesden–Popper 2D perovskites with linear (<italic>n</italic>-BA) and branched (iso-BA) butylamine as spacing cations have been studied by using transient absorption time-resolved photoluminescence spectroscopies.
Chemical absorption using amine–based solvents have proven to be the most studied, as well reliable and efficient technology for capturing carbon dioxide (CO2) from exhaust gas streams synthesis in all combustion industrial processes. The application of single especially very reactive monoethanolamine (MEA) is associated with a parasitic energy demand solvent regeneration. Since regeneration accounts up three–quarters plant operating cost, efforts its reduction prompted idea blended amine...
We investigated the excited-state dynamics of CH3NH3PbBr3 perovskite nanoparticles (NPs) and bulk crystals under various excitation intensity regimes using transient absorption spectroscopy. confirmed sub-band gap hole trap states with optical transition to conduction band in both samples. In crystals, is independent pump intensity. However, NPs, pronounced dependence appears. At low intensities, do not affect due potential barrier between photogenerated holes surface states. When density...
