Autor: Krahne, R., Chilla, G., Schueller, C., Carbone, L., Kudera, S., Mannarini, G., Manna, L., Heitmannb, D., Cingolani, R.

Publikováno v: Nano Lett.; (Letter); 2006; 6(3); 478-482.

We investigated CdTe nanocrystal tetrapods of different sizes by resonant inelastic light scattering at room temperature and under cryogenic conditions. We observe a strongly resonant behavior of the phonon scattering with the excitonic structure of

Formation of Large 2D Arrays of Shape-Controlled Colloidal Nanoparticles at Variable Interparticle Distances

Autor: Ullrich, S., Scheeler, S., Pacholski, C., Spatz, J., Kudera, S.

Publikováno v: Particle & Particle Systems Characterization

A method for the production of homogeneous layers of nanoparticles of arbitrary shape is presented. The method relies on a ligand exchange with a functionalized polymer and a subsequent self-assembly of a thin film on the substrates. The interparticl

Shape- and phase-controlled ZnSe nanocrystals are synthesized in hot mixtures of long-chain alkylamines and alkylphosphines. The variation in the rate of precursor addition, down to low and controlled levels, allows the nucleation, as well as the gro

Optical spectroscopy in the UV/VIS and mid-IR spectral range was applied for a quantitative analysis of ligand exchange in CdSe semiconductor nanocrystals. CdSe cores from a single synthesis run were used for the study in order to ensure identical st

Colloidal hybrid nanoparticles with blebs of II-VI and IV-VI particles on top of FePt particles were successfully grown. Whereas in the case of XE = CdS, ZnS, PbS and CdSe, FePt-XE dimer structures were successfully obtained, the growth failed for XE

We demonstrate catalytic and seeded shape-selective growth of CdSe nanostructures by a steady-state vapor-transport process. By varying the powder and sample temperatures, we observe a transition from a regime where catalytic growth is dominant to a

We present transient absorption studies with femtosecond time resolution on the electron-hole dynamics in CdTe tetrapod nanostructures. Electron-hole pairs are generated by optical excitation in the visible spectral range, and an immediate bleach and
