Guwahati, May 31 -- Indian Institute of Technology Guwahati Researchers have developed an advanced light-emitting perovskite nanomaterial that could improve protection against fake currency, forged documents, and other counterfeit products.

To achieve this, the research team has developed nanocrystals capable of producing light-based security patterns that cannot be replicated using traditional printing and imaging methods.

The findings of this research have been published in the prestigious Advanced Optical Materials journal, in a paper co-authored by Prof. Saikat Bhaumik, Assistant Professor, in collaboration with Prof PK Giri, Professor, and their research scholars, Latika Juneja and Garima Choudhary, from the Department of Physics a...
