Solid state lighting is transforming general illumination with the promise of dramatic energy savings through widespread adoption. In order to maximally realize such benefits, lighting technologies must address human centric aspects such as light quality and color rendering, as well as the environmental impacts of the chosen solutions. Our Materials Team aims to address these critical aspects by developing new color-converting materials for the solid-state lighting market.

About our Materials Team

Our team consists of technicians, physicists, and chemists with a strong background in research and development. The main expertise of the Materials Team is in the field of rare-earth doped nanomaterials (“nano-phosphors”), but we also have experience with alternative materials like Quantum Dots and Perovskites. Due to the fundamental nature of the projects we often team up with world-leading university groups, and also have strong connections and collaborations with industrial partners to advance our projects towards scale-up and commercialization.

Any sufficiently advanced technology is indistinguishable from magic.

Our Main Technology

Our main technology delivers new narrow-band red emitters, which have the promise to deliver significantly increased light output for warm white LEDs, while ensuring high color quality light. Currently, we are focusing our work around blue-excitable Eu3+ as line-emitter for warm white LEDs. Eu3+ is known for its excellent emission properties for white light, but its weak absorption in the blue prevents these ions to be used for LEDs. Our fundamentally new concept of inter-particle energy transfer at the nanoscale solves this, by using separate (nano)materials for absorption and emission events. Seaborough has demonstrated the feasibility of this technology with various different materials and is currently working on delivering warm white LED demonstration devices.


Our labs are situated in one of the “Matrix Innovation Buildings” at the Science Park in Amsterdam, which is a great environment for young technical companies. The campus offers many advanced shared research facilities such as an electron microscopy center, as well as the possibility to have our own lab space. In these, we are fully equipped to perform materials synthesis and optical characterization of luminescent (nano)materials.

Public Funding

Our “EuroLED” program has been granted a Horizon 2020 Eurostars subsidy under the grant number EUROSTAR.2018.34. We have also several projects running in collaboration with the group of Prof. Andries Meijerink from Utrecht University which are supported by the Dutch Research Organisation NWO.

Our solutions


We developed nanocrystalline YAG:Ce with tunable particle sizes down to sub-10 nm, with quantum yields as high as 100%. This demonstration allows for new applications within and beyond the field of lighting, and defeats the common misconception of an intrinsic trade-off balance between crystallinity and particle size and shape!

A scientist looking at the light spectrum


Seaborough's EuroLED technology is a groundbreaking phosphor technology that offers a radically new approach to designing the optical properties of luminescent materials. We achieve this by utilizing separate materials for absorption and emission events, which means that they can be independently adjusted to suit any desired application.

Optical Characterization Service

Do you need reliable optical measurements of luminescent materials? Do you have (nano)phosphor materials, quantum dots, perovskites, or other luminescent samples which need to be optically characterized? Then Seaborough has the solution with a measurement setup that is validated according to industrial values.
