[12p-S201-5] Charge Transfer Dynamics in Plasmon Materials and Perovskite Single Crystals
Keywords:nanomaterial, Charge transfer, Laser spectroscopy
Nanomaterials that strongly interact with light to promote electric power generation, enhancement of chemical reactions, and optical amplification are attracting attention. Dynamics of interparticle electron transfer of indium selenide nanoparticles modified with gold nanoparticles and mechanism of laser oscillation phenomenon occurring under high carrier density conditions in methylammonium lead bromide perovskite microcrystals revealed by femtosecond transient absorption spectroscopy will be discussed in terms of carrier lifetime, transient electronic states, spatial distribution of charges, and charge transfer rate.
