IR Visible Phosphors for Real-Time Product Verification and Authentication
IR Visible Phosphors are upconverting ceramic particles that emit visible light when excited by near-infrared (980 nm) illumination. This anti-stokes shift enables rapid, non-destructive authentication using low-cost IR light sources.
Available in red, green, blue, yellow, purple, and white emissions, these phosphors are ideal for low-security applications and quick quality control checks where simple visual verification is sufficient.
While effective on their own, IR Visible Phosphors can also be combined with Microtrace technologies such as Microtaggant® Identification Particles or Enhanced Phosphors to create layered, robust authentication systems.
How It Works
Microscopic particles absorb near-infrared light and emit a distinct visible color. This upconversion luminescence provides immediate visual confirmation without complex equipment.
Detection & Field Verification
Authentication is rapid, non-destructive, and requires only a basic 980 nm infrared light source, such as a laser pointer or LED. The resulting visible emission can be observed with the naked eye, enabling immediate and reliable product validation in the field using simple tools.
Proven Applications
Microtrace phosphors are used in:
- Authenticating consumer packaging and labels
- Identifying textiles and clothing tags
- Marking bulk materials for quality control
- Adding overt features to security labels
- Serving as a base layer in multi-tiered systems
Seamless Integration
These phosphors are compatible with multiple media:
- Phosphor powders for direct use
- Plastic masterbatches for molded parts
- Security inks and coatings
- Yarns, textiles, and printed labels
They remain stable under typical processing conditions, ensuring consistent performance without compromising material integrity.
