UV and IR Phosphor Technology for Visible Authentication
When conventional phosphors fall short, Microtrace Enhanced Phosphors deliver a visibly distinct, multi-spectral solution for advanced product authentication and supply chain traceability.
These proprietary particles emit multiple visible colors in response to both infrared and ultraviolet light, enabling layered, high-security authentication from a single particle. Unlike traditional flood-coated phosphors, Enhanced Phosphors maintain separation between particles, allowing for controlled color mixing and complex optical signatures.
Exclusive to Microtrace, Enhanced Phosphors can be combined with Microtaggant® Identification Particles for added protection. Integrated into raw materials, adhesives, or labels, they enable rapid, reliable verification with low-cost detection tools and produce a visible response detectable by the unaided eye.
How It Works
Enhanced Phosphors respond to both infrared laser excitation and ultraviolet light, enabling a single particle to emit multiple distinct visible color responses. This dual-trigger capability creates complex, covert authentication features that are extremely difficult to replicate. When combined with a custom Microtaggant® code, they add another layer of security and enable rapid in-field product verification.
On-the-Spot Verification
Field authentication uses affordable tools such as UV lights and infrared lasers for rapid, non-destructive verification, delivering immediate product validation at any point in the supply chain.
Proven Applications
Enhanced Phosphors are ideal for:
- Plastic parts and components
- Adhesives and masterbatch formulations
- Security inks and covert labeling
- Security labels
- Shrink sleeves and plastic packaging
Seamless Integration
Available as powder, plastic masterbatch, or labels, Enhanced Phosphors integrate easily into existing manufacturing processes. Compatible with standard production workflows and low-cost detection tools, they provide a practical and scalable option for enhanced product protection.
