Phosphate favors the biosynthesis of CdS quantum dots in Acidithiobacillus thiooxidans ATCC 19703 by improving metal uptake and tolerance
(Frontiers Media, 2018-02)
Recently, we reported the production of Cadmium sulfide (CdS) fluorescent semiconductor nanoparticles (quantum dots, QDs) by acidophilic bacteria of the Acidithiobacillus genus. Here, we report that the addition of inorganic ...

Designing spatial correlation of quantum dots: towards self-assembled three-dimensional structures
(Iop Publishing Ltd, 2008-01-09)
Buried two-dimensional arrays of InP dots were used as a template for the lateral ordering of self-assembled quantum dots. The template strain field can laterally organize compressive (InAs) as well as tensile (GaP) ...

SAXS and UV-Vis combined to Quick-XAFS monitoring of ZnO nanoparticles formation and growth
(Taylor & Francis Ltd, 2011-01-01)
Time-resolved X-ray absorption-fine structure (Quick-XAFS) and UV-Vis absorption spectroscopies were combined for monitoring simultaneously the time evolution of Zn-based species and ZnO quantum dot (Qdot) formation and ...

Revisiting the ZnO Q-dot formation toward an integrated growth model: From coupled time resolved UV-Vis/SAXS/XAS data to multivariate analysis
(2017-01-01)
Herein we discuss in depth the mechanisms of growth of ZnO quantum dots prepared from zinc oxyacetate ethanolic solutions by LiOH addition. The nucleation, growth and aggregation of ZnO nanocrystals were unambiguously ...
Photoinduced charge separation in organic-inorganic hybrid system: C60-containing electropolymer / CdSe-quantum dots
(Pergamon-Elsevier Science Ltd, 2015-05)
A photoactive interface is formed between an electrochemical generated organic polymer film and CdSe quantum dots. The specifically designed and synthesized 3,4 ethylenedioxythiophene electroactive monomer, holding C60 ...
Surface modification of ZnO quantum dots by organosilanes and oleic acid with enhanced luminescence for potential biological application
(2017-01-01)
Luminescent ZnO-QDs is a promising candidate for biological application, especially due to their low toxicity. Nevertheless, colloidal ZnO-QDs prepared by sol-gel route are unstable in water and incompatible with lipophilic ...
