Deactivation Processes: Jablonski Diagram

1.0K
Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...

Radical Chain-Growth Polymerization: Overview

2.8K
Chain-growth or addition polymerization is successive addition reactions of monomers with a polymer chain. In radical chain-growth polymerization, the reaction proceeds via a free-radical intermediate. The free radical is formed from radical initiators, which spontaneously generate free radicals by homolytic fission. Organic peroxides (such as dibenzoyl peroxide, as shown in Figure 1) or azo compounds are popular radical initiators. A low concentration ratio of radical initiator to monomer is...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Quantum Chemistry

Background:

  • Coupled colloidal quantum dot (CQD) dimers are artificial molecules formed from fused core/shell semiconductor nanocrystals.
  • Epitaxial connections with coherent lattices enable electronic coupling and wave function hybridization between neighboring quantum dots.

Purpose of the Study:

  • To introduce a colloidal approach for controlling neck formation at the interface between CQDs in artificial molecular constructs.
  • To tailor the neck barrier in prelinked homodimers formed via fusion of CdSe/CdS CQDs.

Main Methods:

  • Investigating the effects of reaction time, temperature, and excess ligands on neck formation.
  • Utilizing an intraparticle ripening mechanism to control neck filling while avoiding interparticle ripening.
  • Examining the role of surface ligand passivation and the relative orientation of CQDs on neck growth.

Main Results:

  • Neck filling follows an intraparticle ripening mechanism under mild conditions.
  • Surface ligand passivation is crucial for activating surface atom diffusion to the neck region.
  • Neck filling degree depends on CQD relative orientation; homonymous plane attachment facilitates neck growth.
  • Observed red-shift in absorption and fluorescence attributed to enhanced wave function hybridization in CQD dimers, supported by quantum calculations.

Conclusions:

  • The developed colloidal approach offers precise control over the interface in CQD dimers.
  • Fine-tuning the particle interface allows for controlled tailoring of electronic coupling and wave function hybridization.
  • This method provides a powerful tool for engineering the properties of CQD-based artificial molecules.
