How fine oxides & YAG phosphors impact LED performance

LED technology: a sustainable lighting & display solution

LED chips

Light Emitting Diodes (LEDs) have revolutionized various industries, by providing energy-efficient solutions with less environmental impact than traditional lighting for a wide range of applications, including display screens, car displays and lightings, electronics and smart devices.

Thanks to to the direct conversion of electrical current into light (optical radiation) within the semiconductor material, LEDs exhibit this remarkable level of efficiency. However, a significant portion of the electrical power is also transformed into heat during the process.

High Purity Alumina, YAG & nanomaterials role in advanced LED technology

High purity alumina powder

High Purity Alumina (HPA) plays an essential role in producing the substrate, which serves as a foundation for the LED chip, affecting its overall performance, thermal management, and efficiency. Thanks to its exceptional ability to resist high temperatures, conduct heat efficiently, and insulate against electrical conductivity, LED lights can operate at their maximum potential.

As a highly efficient heat-dissipating component, High Purity Alumina (HPA) has contributed to the LED technology sustainability. Indeed, by maintaining LEDs at optimal temperatures, they maximize their performance and extends their operational lifespan, about 30,000 hours, equivalent to 6 hours of daily illumination for 12 years.

HPA has also influences the optical performance of LED lights, particularly in applications demanding color purity and accuracy. Its uniform crystal structure enhance light diffraction and color consistency in applications like display screens and specialized lighting.

Beyond HPA, Baikowski® also manufactures phosphors, used among other things for generating a broader spectrum of colors, such as its submicronic YAG product that offers a natural-looking white light. For instance, it is used in white LEDs and plasma display panels, as well as adaptive headlights to create different colors and intensities of light depending on the driving situation and the environment.

💡 As technology continues to evolve, Baikowski® finely-tuned oxides solutions and Mathym® advanced nanomaterials, that offer high crystallinity and controlled specific surface area, will have a role to play in the progress of emerging optics applications like mini-LED and micro-LED displays.💡

Integrating the superior performances of Mathym® nanoparticles, such as zilight®  into nanoscale structures or coatings, not only enables the miniaturization of optical devices, but also facilitates integration with other technologies, paving the way for the development of compact and multifunctional  LED lighting solutions. Learn more about optical coating with zilight®, including case studies, in our dedicated white paper.

Ceramic nanofillers

What is the purpose of ceramic nanofillers?

Nanofillers are nanoparticles of oxides embedded into a matrix of diverse materials (polymers, resins, metal…). The “classical” nanofillers are meant to lower the cost of a material by replacing a higher value material. Furthermore, ceramic nanofillers have the benefit of strengthen the physical properties of the matrix, namely its mechanical, optical or thermal properties.

Moreover, we’ll show here a new type of nanofillers, designed for high performance applications. We are talking about the agglomerate-free nanomaterial dispersions.

Properties of innovative ceramic nanofillers

The agglomerate-free nanomaterials dispersed in various media are bringing outstanding properties:

  • High solid loading
  • High transmittance
  • Low viscosity.

Mathym® and Baikowski® are producing several nanoparticles, which can be used as nanofillers. Here are some examples including high purity alumina (Al2O3) nano-dispersions, ceria (CeO2) and zirconia (ZrO2), as known as zilight® for Mathym:

Mathym Nanoparticles dispersed Al2O3, TiO2, CeO2, ZrO2

The nanoparticles are agglomerate-free and delivered as a suspension. They are also known as nano-dispersions. Well dispersed, these nanoparticles used as nanofillers are solving some paradoxes:

filyxio®, YbF3 nanoparticles Mathym

  • Radio-opacity / High transmittance, especially for the product YbF3 of Mathym, filyxio®
  • Low sintering temperature / High density of the ceramic
  • High refractive index / Low light scattering

Hence, the upper properties find their applications in several markets such as medical, technical ceramics, electronics, optronics…
