Lasers and optical amplifiers based on solution-processable materials have been long- desired devices for their compatibility with virtually any substrate, scalability, and ease of …
Organic–inorganic lead-halide perovskites have been the subject of recent intense interest due to their unusually strong photovoltaic performance. A new addition to the perovskite …
The field of nanocatalysis (in which nanoparticles are used to catalyze reactions) has undergone an exponential growth during the past decade. Two types of studies have been …
We report ultra-efficient multiple exciton generation (MEG) for single photon absorption in colloidal PbSe and PbS quantum dots (QDs). We employ transient absorption spectroscopy …

This review seeks to extend the scope of both the experimental and theoreticalwork carried out since I completed my 1993 review on the electronic, optical, andto a lesser extent, the …
Low-dimensional semiconductor structures, often referred to as nanocrystals or quantum dots, exhibit fascinating behavior and have a multitude of potential applications, especially …
MA El-Sayed - Accounts of chemical research, 2004 - ACS Publications
As the size of material becomes equal to or falls below the nanometer length scale that characterizes the motion of its electrons and thus its properties, the latter become sensitive …
