What are TADF materials and why are they important in OLED technology?
TADF (Thermally Activated Delayed Fluorescence) materials are advanced organic emitters that enable the use of both singlet and triplet states for light emission. This significantly enhances the quantum efficiency of OLEDs while eliminating the need for precious metals such as iridium or platinum.
How does the TADF mechanism work?
TADF utilizes a thermally activated reverse intersystem crossing (rISC) process between triplet and singlet states. This allows triplet excitons to be recovered and converted into light-emitting singlets, resulting in quantum efficiencies of up to 100%.
What are the benefits of using TADF emitters?
TADF emitters offer high efficiency, lower energy consumption, no need for heavy metals, and the ability to achieve pure emission colors—including deep blue. They are ideal for applications requiring high performance and durability.
Can TADF replace phosphorescent emitters?
Yes, TADF emitters are a viable alternative to iridium and platinum complexes, especially for blue and green emission. In some cases, they also offer better stability and more predictable emission properties.
What TADF materials do we offer at Noctiluca?
We supply carefully selected high-purity TADF materials optimized for OLED emissive layers. Our offer includes blue, green, yellow, and orange emitters ready for R&D testing and industrial prototyping.
Are Noctiluca's TADF materials available in sublimed form?
Yes, many of our TADF compounds are offered in sublimed form, ensuring the highest purity and homogeneity — critical for next-generation OLED structures.
What purity levels do we offer for TADF emitters?
Typical purity for our TADF materials is ≥99.5% (HPLC), with sublimed versions reaching ≥99.9%. All products come with full analytical documentation.
Do we support customers in selecting the right TADF emitter?
Yes, we offer technical consulting to assist in selecting TADF emitters, including analysis of energy levels, emission type, and compatibility with other OLED layers.
For which applications do we particularly recommend TADF compounds?
TADF emitters are especially recommended for OLEDs used in mobile displays, TVs, lighting systems, and microdisplays where brightness and longevity are essential.
Are our TADF materials suitable for industrial applications?
Yes, many of our products have been validated under pilot-scale production conditions. We supply materials to tech firms, display manufacturers, and development centers conducting implementation projects.
What are the typical energy levels of our TADF emitters?
The HOMO and LUMO levels of our TADF compounds are designed to allow efficient charge injection and recombination. Specific values depend on emission color and material structure.
Can TADF samples be ordered for R&D testing?
Yes, most of our TADF emitters are available in lab-scale quantities (from a few mg), with the option to scale delivery according to project phase and customer demand.
Can we provide project-specific TADF materials?
Yes, in addition to catalog products, we offer custom synthesis of TADF materials tailored to client specifications — in terms of energy levels and emission characteristics.
What analytical techniques do we use to validate TADF quality?
We use advanced analytical techniques including NMR, HPLC, UV-Vis, PL, TGA, and DSC. For sublimed materials, we also perform thin-film stability and morphology testing.
