Magic-sized clusters represent materials with unique properties at the border between
molecules and solids and provide important insights into the nanocrystal formation process …

Spectroscopy of shallow donors is a tool to test theoretical models and to reveal properties
of semiconductors. In this work we consider intra-shallow impurity transitions by studying a …

We report on the optical spectroscopy of the spin of two Co atoms in a quantum dot and
interacting with a single exciton. Spectra of quantum dots containing two Co atoms are …

Herein we explore the opportunities arising from combining magnetic properties and
porosity in metal–organic materials. In this sense, we have prepared an adenine based …

We study the influence of the addition of the Co ions on the spin-lattice relaxation rate in the
(Cd, Mn) Te system. The magnetization relaxation is measured by time-resolved …

We present a polarization-resolved photoluminescence study of the exchange interaction
effects in a prototype system consisting of an individual Fe 2+ ion and a single neutral …

Light trap** is a crucial mechanism for synchronization in optical communication.
Especially on the level of single photons, control of the exact emission time is desirable. In …

We present the basic properties of a new physical system: an individual V2+ ion embedded
into an individual quantum dot. The system is realized utilizing molecular beam epitaxy and …

Owing to exchange interaction between the exciton and magnetic ion, a quantum dot
embedding a single magnetic ion is a great platform for optical control of individual spin. In …

In the present study, zero field splitting (ZFS) parameters are investigated for Mn (II) ion
doped perovskites, viz. PbTiO _ 3, BaTiO _ 3 PbTiO 3, BaTiO 3 and SrTiO _ 3 SrTiO 3. The …
