Dear colleagues,
You are cordially invited to the Institute of Physics Belgrade
seminar, which will be held on Friday, 14 August 2026 at 12:00 in
the library reading room "Dr. Dragan Popović" of the Institute of
Physics Belgrade. The talk entitled
On-the-fly soft X-ray spectroscopies of isolated and solvated
nanoparticles: probing metal–molecule interfaces on plasmonic
nanoparticles and exploring new photovoltaic nanomaterials
will be given by Dr Aleksandar Milosavljević (Synchrotron Soleil,
France). The abstract of the talk:
A state-of-the-art experimental setup at the PLEIADES beamline
(SOLEIL Synchrotron, France) for X-ray Aerosol Photoelectron
Spectroscopy (XAPS) of nanoparticles isolated in vacuum will be
presented [1,2]. The nanoparticle beam is generated from a
colloidal solution, focused by an aerodynamic lens, and crossed
with the photon beam in front of a hemispherical analyzer. This
arrangement offers several advantages over table-top techniques:
it completely avoids substrate influence and radiation damage,
allows direct alignment to the vacuum level [3], and enables depth
profiling via tunable photon energy. Moreover, using soft X-rays
provides exceptional sensitivity to the nanoparticle surface.
I will present and discuss recent results related to the
electronic structure of new photovoltaic materials [2] and
light-induced chemistry on functionalized metallic plasmonic
nanomaterials [4]. I will briefly discuss perspectives on
combining XAPS with liquid jet spectroscopy on PLEIADES, utilizing
mass/charge-selected X-ray spectroscopy to investigate ligands
alone, and probing light-activated nanoparticles in situ.
This activity is supported by the Science Fund of the Republic of
Serbia, #Grant No. 230, Aerosols of copper-silver based
nanomaterials for absorbers in solar cells - Aerosol4solar.
