Fluorescent Inks for Security Applications

Fluorescent Inks for Security Applications

CSIR-NIIST uniquely developed dual colour emitting inorganic phosphors for specialized applications. In the daylight conditions, these phosphors do not emit any noticeable light. Under UV lights of different wavelengths, the phosphors show different emission colours. The developed security inks using these phosphors produced various writings on different surfaces, including currency notes and QR codes. The above technique can prevent fraud and duplication of logos, currency notes and documents.

  • Advantages :
    • CSIR-NIIST developed inorganic phosphor emits blue and red colour at various UV lights
    • This technology of dual emitting inorganic phosphors under various UV lights could provide additional protection to crucial products to secure their originality
    • Since the phosphor emission and lifetime are highly stable, hence these are perfect for anti-counterfeiting applications, particularly in various currencies and codes
