Although the implanted Ge depth profile is distributed over almost the whole SiO{sub}2 layer, a very narrow band (typical width 5 nm) of Ge nanoclusters very close but well-separated to the Si/SiO{sub}2-interface is formed by self-organization under specified annealing conditions. A possible...
Today the band is announcing the third album in their Nanocluster series, out in February 2025 (pre-order). The release is a mid-Atlantic melting pot of ideas that have created a brand new third way. The album sees a collaboration between the European post-punk electronic discipline of Immer...
This is particularly true for nanoclusters because these have significant spectral contributions also outside the broad plasmon band that is usually associated with them. The reduction of palladium, gold, and silver ions and the formation of the corresponding clusters is monitored in the presence of ...
Raman spectroscopy was used to examine the intensity ratios (ID/IG) of the D-band to the G-band in the samples, indicating the surface defects in the carbon material (Fig. S10). The results showed that the ID/IG ratio of CFS-ACs/CNT was smaller than that of CFO-p/CNT. Fewer ...
In contrast, larger gold nanoparticles with a diameter greater than 2 nm have a continuous electronic energy band. Gold nanocluster provides several advantages, such as massive luminescent and optical characteristics, high stability, and biocompatibility. Gold nanoclusters show cytotoxic effects in ...
The optical adsorption spectrum of the nanocluster (in CH2Cl2, 0.1 mM) shows a strong peak at 515 nm and a weak tail band at 600–700 nm (Fig.4a); the HOMO-LOMO gap is ca. 1.4 eV (Supplementary Fig.8). Furthermore, the photoluminescence of the nanocluster was studied using...
In addition, we have measured the nanocluster-size dependent photoemission spectra in the valence-band region. From line shape analysis of Au4f X-ray photoemission spectra, Au4f core-level spectra of the dendrimer-encapsulated Aunanoclusters reflect the size dependent chemical-states. From these ...

intensity preserved upon 0.04 mJ UV irradiation. This photo bleaching process can be correlated with the first stage of photochromism, wherein the absorption at 340 nm is suppressed. Further UV irradiation resulted in the emergence of a broad PL band centered at 532 nm and this change ...
The climbing nudged elastic band (CI-NEB) method78 is used to locate the tran- sition states. Six intermediate images are used in each CI-NEB pathway. Vibrational frequencies for the initial, transition and final states of the reactions are calculated and the transition state is confirmed from...
