Ultra Bright Inorganic Phosphors for Forensic Finger Print Detection

NIIST developed phosphor nanoparticles have special fluorescent properties that make them compatible with fingerprint residues. Ultrafine phosphor particles synthesized via a scalable route are efficiently glowing under UV lights. The particle sizes are matched well with the finger ridges and valleys. These nanoparticles are perfect for certain security and forensic applications.

NIIST has developed phosphor nanoparticles with unique fluorescent properties, ideal for fingerprint residue detection. These ultrafine phosphor particles, synthesized through a scalable route, emit a strong glow under UV light and are specifically designed to match the size of finger ridges and valleys, making them highly effective for forensic analysis.

• Submicron particles with intense red and green glow under the UV light are obtained.

• A rapid and optimized microwave-assisted route has been adopted for synthesis.

• These promising phosphors exhibited excellent visualization regardless of the background interference and limit the risk of duplication and are highly reliable.

• Highly suitable for the visualization of latent fingerprints on various substrates.
