Materials for Solid-State Lighting Solutions
Innovative LED phosphor materials from Merck
As reliable partner to the global solid-state lighting industry, Merck develops various phosphor materials for more efficient solid-state lighting solutions. Under the brand name isiphorTM, we offer innovative luminescent materials for LED production to make your illumination ideas come true. A big range of color-on-demand concepts from warm to cold white light is readily available.
Your advantages - High efficiency and less energy consumption
Using extensive know-how and manufacturing expertise together with the most advanced process technology, Merck creates lighting materials with homogeneous morphology and particle distribution that are superior to conventionally produced lighting materials. Our phosphors are especially homogeneous in form and size, enabling homogeneous phosphor conversion layers with high efficiency, significantly less light scattering, and even less energy consumption.
Applications - Color on demand
Merck's wide range of improved phosphor technologies comprise different material platforms, e. g. ortho-silicates and garnet-type phosphors. We offer a broad material portfolio of green, yellow and orange-colored lighting materials, each with different particle sizes. Our materials meet the requirements of all LED market sets including LED backlighting and general lighting applications.
Through different lighting material compositions, the color temperature of the light can be flexibly modified as desired - color on demand. For instance, white light can be generated in cold or warm shades, both stable and reproducibly. In realizing your individual color-on-demand concept you can fully rely on Merck: Our developers will support you throughout the entire process from the initial idea to successful implementation.
Using phosphors from Merck, you don't have to ponder over feasibility - just concentrate on imagining what would look great.
The technology - White and colored LED light
Originally invented in the first half of the 20th century and commercially introduced in the 1960s, LEDs are finally about to revolutionize the lighting market. LEDs present many advantages over traditional light sources: They have a very high energy saving potential, do not contain any environmentally unfriendly heavy metals and have superb longevity.
The color of LEDs depends on the light-emitting semiconductor material used. High-brightness blue LEDs based on gallium nitride first became widely available in the late 1990s; today they are used to produce most high-intensity white LEDs as well. Broad-spectrum white light is generated by coating the blue LED with luminescent colored phosphor materials. Merck develops highly efficient phosphor lighting materials capable of increasing the amount of generated light and emitting white light with a warm and pleasant shade.
