摘要：
Quick change: Femtosecond optical pump-probe spectroscopy is used to study the photoswitching dynamics of Fe III spin-crossover nanocrystals. Results indicate that up to 10% of the molecules can be photoswitched from low-spin to high-spin states within less than one picosecond. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
