Correlation between structural and optical properties in semiconductor nanorods

 

 

 

 

Importance of directly correlating the structural and optical properties of semiconductor nanorods

Semiconductor nanorods (NRs) are highly attractive materials for many devices including high-efficiency light emitting diodes and for hydrogen harvesting. During commercial device development, it is critical to determine how the structure of the NRs impacts their functional properties. 

To this end, researchers frequently employ photoluminescence to measure the optical properties of hundreds to thousands of NRs, and electron microscopy to reveal the structure and composition at atomic resolution. Historically, there was no direct correlation between these two techniques. However, recent investigations demonstrate that direct correlation of the optical properties (using the unique nanometer-scale resolution of cathodoluminescence) with structural properties is critical for researchers to draw unambiguous, and avoid incorrect conclusions.
