The discovery of carbon fullerene cages and their solids opened a new avenue to build
materials from stable cage clusters as “artificial atoms” or “superatoms” instead of atoms …

Laser excitation of nanometer-sized atomic and molecular clusters offers various
opportunities to explore and control ultrafast many-particle dynamics. Whereas weak laser …

The achievement of significant photoluminescence (PL) in lanthanide ions (Ln3+) has
primarily relied on host sensitization, where energy is transferred from the excited host …

High resolution XPS spectra (4f) of mass-selected AuN-clusters supported by a thin natural
silica layer are presented in the size range N= 1–35 atoms per cluster. The XPS binding …

In this work, a novel 3D graphene framework/Bi nanoparticle (GF/BiNP) film was fabricated
with a facile preparation route. 3D graphene framework with porous structures was …

Present performance and future development of the free-electron lasers (FELs) in Hamburg—
FLASH for the extreme ultraviolet and the European XFEL for the soft and hard x-ray …

In this work, we report a facile and green strategy for in situ and one step preparation of a
novel 3D graphene/gold (G/Au) film. Triggering with unique driving force from hydrothermal …

We report the systematic appearance of a plasmon-like optical absorption feature in silver
clusters protected with 2-phenylethanethiol (PET), 4-flurothiophenol (4-FTP) and (4-(t-butyl) …

Abstract Excitation‐wavelength‐dependent (Ex‐De) emitters are a fascinating category of
luminescent materials whose emission properties vary with the wavelength of the light used …

We report on the theoretical study of laser-assisted attosecond photoemission from metals.
The full time-dependent quantum approach reveals the role of the resonant interband and …
