X-ray study reveals how lead sulphide particles
self-organise in real time

9th August 2021by admin0

The structure adopted by lead sulfide nanoparticles
changes surprisingly often as they assemble to form ordered
superlattices. This is revealed by an experimental study that has
been conducted at DESY’s X-ray source PETRA III. A team led by the
DESY scientists Irina Lokteva and Felix Lehmkühler, from the
Coherent X-ray Scattering group headed by Gerhard Grübel, has
observed the self-organization of these semiconductor nanoparticles
in real time. The results have been published in the journal
Chemistry of Materials. The study helps to better understand the
self-assembly of nanoparticles, which can lead to significantly
different structures.

    The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
