Dual-signalled magneto-optical barcodes with lanthanide-based molecular cluster-aggregates.

Published in: Nanoscale (2023)

A proof-of-concept for magneto-optical barcodes is demonstrated for the first time. The dual-signalled spectrum observed via magnetic circular dichroism spectroscopy can be used to develop anti-counterfeiting materials with extra layers of security when compared with the widely studied luminescent barcodes.
