IR Visible Phosphors

These phosphor nanoparticles are an easy-to-identify option for quality-control issues or low-level security applications.

What are infrared-to-visible phosphors?

Upconverting phosphors are microscopic ceramic particles that provide a color response when excited by 980 nm invisible light.  When these up-converting particles are illuminated with an infrared light, they emit a colored light that is visible to the human eye. This is also known as an anti-stokes shift.

Customize with your choice of color

With a variety of colors to choose from—including red, yellow, green, blue, purple and white—Microtrace can deliver phosphor powder, plastic masterbatch, yarn, security ink or in a security label. IR phosphor is commonly used for consumer packaging, clothing tags and incorporation in bulk materials because it’s easy to use, inexpensive and provides a visible response.

Consider a complete security solution

These luminescent phosphors represent the lowest level of security that Microtrace offers and don’t provide total security—but sometimes they are enough. Others often position IR up-conversion phosphors as a security solution, however, phopsphor for sale is widely available and can be easy duplicate.

At Microtrace, taggants are uniquely encoded materials or chemistries that are virtually impossible to duplicate. Up-converting phosphors can be added to Microtaggants for a multi-level security solution. Microtrace has a range of phosphor solutions and can help you implement any degree of security, over time, as your needs change.

Microtrace does not recommend up-converting phosphor as a standalone security solution. We offer two more secure options for phosphors you can implement independently:
