Colloidal precipitates

Colloidal precipitates

The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

Background:

Bismuth chalcohalides (BiEX) are emerging materials with potential applications in nanotechnology.
Previous synthesis methods often lack versatility or scalability for producing well-defined nanocrystals.

Purpose of the Study:

To develop a versatile colloidal synthesis for bismuth chalcohalide nanocrystals (BiEX NCs).
To characterize the structural, optical, and stability properties of the synthesized BiEX NCs.
To evaluate their potential for solution-processed optoelectronic devices.

Main Methods:

Colloidal synthesis of bismuth chalcohalide nanocrystals (BiEX NCs, E=S, Se; X=Cl, Br, I).
Structural characterization using X-ray diffraction and electron microscopy.
Optical characterization including band gap determination.
Assessment of chemical stability and colloidal ink formation.
Fabrication and testing of solid films for photoelectrochemical applications.

Main Results:

Successfully synthesized orthorhombic, elongated BiEX NCs, including a new polymorph of BiSCl.
Achieved composition-dependent band gaps across the visible spectrum with high absorption coefficients (>10⁵ cm^-1).
Demonstrated excellent chemical stability and formation of stable colloidal inks.
Produced robust solid films from NCs exhibiting stable photoelectrochemical current densities under solar simulation.

Conclusions:

The developed colloidal approach provides a versatile route to large-scale synthesis of BiEX NCs.
BiEX NCs are stable, highly absorbing nanomaterials suitable for solution processing.
These findings establish bismuth chalcohalides as a promising class of materials for nanotechnology, complementing existing chalcogenides and halides.
