Summary

Story summary

Scanning-Exciton Optical Nanoscopy (SEON) was developed by researchers from Huazhong University of Science and Technology and Zhejiang University.
SEON enables simultaneous mapping of nanoscale light fields and local density of optical states at about 4-nanometer resolution.
The method uses a quantum dot attached to a silica probe to track light interactions.
The findings could advance nanophotonics and quantum optics.
