Overview
Seaborough is a Netherlands-based nanoscience and nanotechnology company focused on luminescent nanomaterials. According to its official website, the company works from nanoscale chemistry through to unusual luminescent materials design, turning scientific ideas into applications by concentrating on research and development, commercialization, and licensing of nano-engineered luminescent and lighting solutions. It describes itself as the only company in the world that creates nanophosphors of adjustable sizes — from less than 20 nanometers to several microns — while ensuring consistent performance. Its stated values are ambition, innovation, and collaboration, and it positions itself as a transparent partner for customers' R&D, marketing, and supply chain teams. Seaborough's product portfolio targets bottlenecks in LED lighting and displays, anti-counterfeiting, and related areas. Its flagship offerings include EuroLED®, a patented warm-white nano-engineered Eu³⁺-based phosphor solution that the company says provides stability, low saturation, color tunability, and 10% to 20% more lumens per watt for CRI 80–95 LED applications; Lumicrypt®, an anti-counterfeiting material based on Seaborough's proprietary IFRET technology that uses nano-engineered luminescent pigments with tunable spectral features; and Crystalight®, a nanocrystalline YAG:Ce phosphor with tunable particle sizes down to below 20 nanometers and near-unity quantum yields for advanced lighting and display applications. The company is headquartered in Amsterdam, Netherlands, and operates in the solid-state lighting, display, and security materials markets. It engages with customers through licensing and partnership models rather than only selling finished consumer products, reflecting its role as a materials technology provider. Its team combines physicists, chemists, engineers, and commercial specialists, and its public team listing includes roles such as Director of Research, Director of Product Engineering, CFO, and a Senior Advisor, alongside materials scientists, chemists, and product and marketing staff. Seaborough presents its technologies as designed for impact, scalability, and sustainability, aiming to help customers launch differentiated products that improve lives and are better for the planet. EuroLED® is described as compatible with existing LED manufacturing processes and as undergoing customer validation, indicating a commercialization stage rather than a fully mature mass-market product line. The company's focus on nano-engineered luminescent materials places it in the advanced materials and photonics supply chain that supports the broader LED lighting and display industries.
History
Seaborough is a nanoscience and nanotechnology company based in Amsterdam, Netherlands, focused on luminescent nanomaterials. Public information about its founding and early corporate history is limited; its Wikidata entry describes it simply as an "LED lighting company from Amsterdam." The company has built its identity around the untapped potential of luminescent nanomaterials, working from nanoscale chemistry to unusual luminescent materials design. Seaborough's development has centered on three named technology platforms. EuroLED® is a patented warm-white nano-engineered Eu³⁺-based phosphor solution that replaces traditional phosphor systems with a more efficient red and green phosphor combination. The company states that EuroLED® delivers up to 10–20% more lumens per watt for warm-white CRI 80–95 applications while maintaining color stability, low photo-saturation, and thermal performance, and that it is compatible with existing LED manufacturing processes and undergoing customer validation. Lumicrypt® is based on Seaborough's proprietary IFRET technology and uses nano-engineered luminescent pigments to provide an advanced security solution with tunable spectral features for anti-counterfeiting. Crystalight® is a nanocrystalline YAG:Ce phosphor with tunable particle sizes down to below 20 nanometers and near-unity quantum yields, aimed at advanced lighting and display applications. The company emphasizes that it is the only company in the world that creates nanophosphors of adjustable sizes — from less than 20 nanometers to several microns — while ensuring consistent performance. Its team combines physicists, chemists, engineers, and commercial specialists, and its public team page lists a range of scientific, engineering, and business roles, including a Director of Research, Director of Product Engineering, CFO, and Senior Advisor. Seaborough describes its mission as harnessing nanoscience to redefine luminescence and, together with customers and partners, creating products that improve lives and contribute to a healthier planet. Its business model centers on R&D, commercialization, and licensing of nano-engineered luminescent and lighting solutions, positioning it as a materials technology partner to the LED lighting, display, and security industries rather than a consumer-facing brand.
