Luminescent security Ink- Context

  • Recently, Indian Scientist has developed a highly stable and non-toxic security ink from nano-materials that spontaneously emit light (luminescent) due to its unique chemical properties.
  • Associated benefits: security ink will help in combating the counterfeiting of branded goods, bank notes, medicine, certificates, currency.
    • It is generally used as covert tags to combat counterfeiting.

Luminescent Ink- Key Points

  • Present Issue: Rampant counterfeiting of branded goods, banknotes, medicine, certificates, currency, and other important documents.
  • Luminescent ink: Most of the security inks available today are based on luminescent materials that absorb a high-energy photon and emit a low-energy photon, technically called downshifting.
  • Associated issues:
    • The covert tag is invisible under daylight but becomes visible under UV light.
    • These single emission-based tags are also prone to replication.

 

Luminescent Security Ink: How it is superior to other Luminescent inks?

  • Development of the security ink: Institute of Nano Science and Technology developed non-toxic metal phosphate-based ink with excitation dependant luminescent propertie.
  • Superiority over other Luminescent inks: Unlike others, it is highly stable under practical conditions such as temperature, humidity and light, etc.
  • Chemical composition: The luminescent security ink developed by the researcher is based on lanthanide ions (Ln3+) doped Gd1-xBixPO4 nano-materials.

 

Institute of Nano Science and Technology- Key Points

  • About: Institute of Nano Science and Technology is an autonomous institution of the Department of Science and Technology (DST), Government of India.
  • Mandate: It has been established under the umbrella of NANO MISSION, initiated by DST to boost research and development in the field of Nanoscience and Nanotechnology in India.
  • Mission: It has set a unique mission to work at the forefront of fundamental science together with the development of technologies to address problems of national and global priorities.
