What are dopant materials in OLED technology?

OLED dopants are luminescent active compounds that serve as light emitters within the emissive layer. Their function is to convert excitation energy into light emission of a specific color, with high quantum efficiency and a controlled energy profile.

What types of OLED dopants do we offer?

Our portfolio includes TADF emitters, phosphorescent iridium complexes, and donor–acceptor type emitters. Each class of these materials is used in OLED devices requiring precise emission color control and high efficiency.

What are the main applications of OLED dopant materials?

OLED dopants are used in mobile displays, OLED TVs, microdisplays, decorative lighting, and automotive systems. Key parameters include brightness, efficiency, low operating voltage, and color purity.

What is the difference between TADF and phosphorescent dopants?

TADF dopants do not require heavy metals and rely on the mechanism of thermally activated delayed fluorescence (TADF), whereas phosphorescent dopants (e.g., iridium-based) operate via triplet states through spin-orbit coupling. Both types of dopants can achieve up to 100% emission efficiency, depending on their structure.

What emission colors are available in Noctiluca’s portfolio?

We offer OLED dopants emitting blue, green, red, and intermediate shades (yellow, orange). Materials are available as catalog products or as part of custom synthesis tailored to client-specific projects.

Are the offered dopants suitable for vacuum sublimation?

Yes, many of our dopants are available as sublimed organic compounds, suitable for vacuum deposition and ensuring maximum purity and thin-film homogeneity.

What purity levels do we offer for OLED dopants?

We typically offer ≥99.5% purity (HPLC), and for sublimed materials, even ≥99.9%. Each product is accompanied by full analytical documentation and quality control.

Are Noctiluca’s dopants compatible with common OLED hosts?

Yes, our OLED dopants are designed to be compatible with a wide range of commercial and experimental hosts. We also offer support in host–dopant matching.

Is it possible to order a dopant sample for R&D testing?

Of course. We supply OLED dopants in laboratory-scale quantities (mg–g) and can scale up delivery after successful application validation.

Do we offer custom synthesis of OLED dopants?

Yes, we provide custom synthesis services including the design and synthesis of dopants with specific structure, emission color, energy levels, and compatibility with defined device architectures.

What analytical techniques do we use to assess dopant quality?

We apply advanced analytical methods: HPLC-MS, NMR, UV-Vis, photoluminescence, TGA, DSC, and thin-film testing — especially for sublimation-grade materials.

Are the dopants tested in actual OLED structures?

Yes, many of our materials have been validated in OLED test structures. We can provide application data or collaborate with customers in evaluation testing.

How does a dopant affect emission color and quality in OLEDs?

The dopant determines the exact emission color, quantum efficiency, lifetime, and performance within the entire operating voltage range. The choice of dopant is critical to the quality of the display or light source.

Do we offer support in designing the OLED emissive layer?

Yes, we assist clients in optimizing the EML (emissive layer) by analyzing energy alignment, host compatibility, and the photophysical profile of the entire stack. We act as a technology partner during R&D and pilot phases.

How to order an OLED dopant from our collection?

Just contact our team. Once technical needs are defined, we will prepare a material offer, delivery options, and analytical documentation. We offer flexible cooperation terms for both R&D and industrial partners.
