A world leader in innovative lighting materials and components

Intematix develops and manufactures phosphor solutions that drive the quality and reliability of LED solid-state lighting. We offer the broadest range of phosphors, facilitating full spectrum LED solutions that radiate vivid, stable, attractive light. We draw on our expertise in phosphor to supply ChromaLit remote phosphor. Intematix materials and solutions are found in a complete range of lighting products—from display to general lighting in commercial and residential applications—on a global scale. The unmatched breadth of products offered by Intematix helps to accelerate time-to-market, improve light quality and efficacy and ultimately reduces sytem costs.

What is phosphor?

In the simplest of terms, phosphor is what makes LED light usable. LED chips are intrinsically blue, red or green, with the blue variety of LEDs being the most commonly used in solid state lighting. However, the blue light that they produce is unusable for everyday lighting and must be covered, either coated directly on the chip, or remotely placed, with a phosphor solution.  While the efficiency of an LED is largely controlled by the blue chip, the color quality that we see is almost entirely dependent on the phosphor that is used.  Intematix offers four main types of phosphor to ensure correct color targeting and very high light quality.

  • Silicates offer some of the brightest phosphors, meaning they are the best choices, currently, for displays.
  • NYAG (Garnet) phosphors can be used as a single solution phosphor for industrial or outdoor lighting where is efficiency is the name of the game; not necessarily the quality of light.  However, they can also be combined with other phosphors to make +80CRI quality white light.
  • GAL (Aluminate) phosphors are Intematix proprietary phosphors that can be blended with red phosphor (particularly, the Intematix XR red nitrides) to create some of the highest quality white light currently available in the market - this combination of phosphors (GAL + red) to create white light is patented by Intematix.
  • Red Nitride phosphors are a crucial ingredient to creating high quality light with an R9 value of up to 98. If you want an LED that compares to an incandescent light source in color quality, red nitride is currently a must.
