IMTS Emitters for OLED

Welcome to Efficient Blue

Efficient Blue pioneers next-generation blue OLED technology. By harnessing a novel approach to light emission, we solve the key challenge of OLEDs: enabling efficient, bright, and longer-lasting blue pixels for advanced display and lighting solutions of tomorrow.

Efficient Blue is an R&D Project of Nanomatch and the LEXOS group at IAPP to . We are currently in the Proof-of-Concept stage, demonstrating the proprietary IMTS concept. IMTS circumvents harmful triplets in flurescent OLEDs to enable efficient, durable devices with simple stack designs and low-cost, purely organic materials.

We follow a computer driven rational design approach: Digital twins based on physical models & supported by AI allow us to maximize R&D efficiency, enable rapid design cycles and keep us ahead!

  • Open for Investments

    We are looking for strategic and financial partners to bring IMTS to market! Get in touch to be part of Efficient Blue!

  • First Prototype

    The first prototype shows promising 88.6% singlets generated on the emitter. However, due to exciton cascades, device efficiency is limited at 5%. An improved setup is currently being tested.

  • Start of the Efficient-Blue project

    Efficient Blue is a project between Nanomatch and the LEXOS group at IAPP, TU Dresden, funded by the BMWK Germany via the ZIM program. The project began in February 2024, aiming at a physical prototype by end of 2025.

  • Proof of principle: Validation of the IMTS concept

    The IMTS concept was developed by Nanomatch and demonstrated in computer simulations. We have identified a first set of potential candidates for materials and are now experimentally testing the first batch of devices.

The IMTS Concept

Excitons are formed as singlets or triplets. According to spin statistics, 75% of the excitons formed on fluorescent emitters are triplets, and only 25% are formed in the singlet state. On fluorescent emitters, only singlets can decay radiatively, i. e. emit a photon, while long-lived triplets cannot emit light and potentially cause harm to the system, especially in the blue regime.

Exploiting a commonly overlooked effect in exciton formation allows us to tune singlet-triplet ratio of exciton formation on fluorescent emitters. This is achieved by using emitters with two specific energetic properties and careful alignment with the host material. As demonstrated in digital twins of IMTS OLEDs this leads to internal quantum efficiency (IQE) close to 100%, including the promise of reduced degradation and long OLED lifetime.
