Special Phosphors
Special phosphors are luminescent materials engineered for application-specific requirements. They go beyond standard phosphors used in general lighting and are tailored to meet defined optical signatures, excitation conditions, and environmental constraints.
At Tailorlux, we support customers with special phosphors for advanced technical applications. Our portfolio includes materials emitting in the UV, visible, and near-infrared (NIR) spectral ranges, depending on the target use case.
What we mean by “Special Phosphors”…
“Special phosphors” refers to inorganic luminescent materials designed for specific functional needs rather than mass-market standardisation. Depending on the application, the focus may be on spectral position, bandwidth, stability, lifetime, compatibility with excitation sources, and chemical or thermal robustness.
Instead of positioning the topic around a single product family, this page highlights the broader material space and how we approach tailored solutions.
Application Areas
Special phosphors can be relevant for a variety of applications, for example:
- Optical security and authentication features
- Tracer and marker systems
- Sensors and indicators
- Imaging and detection concepts
- Reference materials for optical read-out systems
The suitability of a phosphor system depends on the specific excitation, read-out, and integration conditions.
Material Characteristics and Design Parameters
Depending on requirements, special phosphors can be tailored with respect to:
- Emission wavelength and spectral fingerprint (UV, visible, NIR)
- Excitation compatibility (e.g., LED, laser, broadband sources)
- Emission bandwidth, intensity, and decay behaviour
- Thermal stability and long-term performance
- Chemical stability and resistance to environmental influences
- Host lattice and dopant design
Particle properties (e.g., size distribution, surface behaviour)
Example: Near-Infrared (NIR) Phosphors
NIR phosphors represent one segment within the broader special phosphor category. They can be designed to emit in the near-infrared range and may be used in optical read-out systems where NIR emission offers specific benefits.
This product area is only one part of the overall special phosphor portfolio and is shown here as an example of how spectral requirements can be addressed through tailored material design.
R&D and Development Options
In addition to existing materials, Tailorlux supports customised phosphor development through collaboration with selected external R&D partners. This enables exploration and adaptation beyond standard product ranges, for example:
- new host lattices and dopant combinations
- customised emission signatures and bandwidth concepts
- application-specific stability or integration requirements
- feasibility studies and early-stage prototyping
Development scope and feasibility depend on technical requirements, target quantities, and timelines, and are clarified during technical consultation.
Technical Consultation
If you have a defined spectral target, excitation source, or integration environment, we can assess suitable material options and discuss development pathways where needed.
Tailorlux sets new standards in digital supply chains and manages to get everywhere with its marking.
So that safety and traceability determine each fiber in a sustainable and transparent way.
At Tailorlux, we offer you a contemporary traceability solution that documents every step from raw material to finished product at the point of sale. Tailorlux technology thus offers you a:
Indestructible marking
Our marking is introduced at the beginning during ginning and is now inseparably bonded to the fibers. And it is completely non-toxic and chemically inert.
Perfected traceability
Our sensor technology is used to read the individual and tamper-proof marking.
Real-time monitoring
Each measurement/verification goes directly to the cloud.
Deep insight into your supply chain
Data is collected and processed by an AI.
Full transparency
Each fiber knows its origin, so that the genuineness of the products can be ensured and guaranteed.
