Background:
- Metal nanocrystals (NCs) exhibit unique properties dependent on their structure.
- Heterogeneities within NC ensembles and characterization limitations hinder understanding structure-property relationships.
- Accurate characterization is vital for designing advanced NCs for diverse applications.
Purpose of the Study:
- To describe intraparticle and interparticle heterogeneities in NC ensembles.
- To compare single-particle techniques for characterizing NC heterogeneities.
- To showcase multimodal approaches for elucidating NC structure-property relationships.
Main Methods:
- Review of intraparticle and interparticle heterogeneities in NCs.
- Detailed comparison of single-particle characterization techniques.
- Case studies employing multimodal characterization of NCs.
Main Results:
- Identification and classification of common NC heterogeneities.
- Evaluation of single-particle techniques for addressing these heterogeneities.
- Demonstration of how combined techniques yield deeper insights into NC behavior.
Conclusions:
- Current single-NC techniques have limitations for comprehensive analysis.
- Development of high-throughput, high-resolution methods and computational tools is needed.
- A proposed workflow can accelerate the design and discovery of novel metal NCs.
