  • Recent advances in thermally activated delayed fluorescence for white OLEDs applications

    摘要： Thermally activated delayed fluorescence (TADF) materials, which can harvest all excitons without utilizing any noble metals to emit light, are becoming the key cornerstone for developing the next generation of organic light-emitting diode (OLED) devices. In recent years, TADF materials are attracting numerous attentions as a new surge of research focuses on both science and industry owing to their high efficiency, low power consumption, and low production cost attributes when applied to white OLEDs. The design and application of TADF in WOLED devices have also experienced the rapid development in fundamental science and industrial technology perspectives. In the present review, the specific reverse intersystem crossing mechanism and evolution of TADF is outlined firstly, and then the latest research progress of TADF-WOLEDs is summarized and discussed. TADF/conventional fluorescence, TADF/phosphorescence, all TADF and TADF exciplex-based WOLEDs are categorized and elaborated in terms of the device structure, working mechanism, efficiency, color-rendering index, etc. Finally, we conclude with the future challenges and opportunities in high-quality TADF devices and application area.

  • Fault Tolerant Control System for Photovoltaic Panels Application

    摘要： The paper presents a solution to control the power delivery system in a microgrid in which the primary energy source is using photovoltaic panels. The proposed mathematical models describe the operation of the main system blocks and are used as reference models in the fault detection mechanism. Using a complex control strategy, the generated power is controlled and the effects of the disturbances which occur in the system, including the faults, are rejected, making the proposed solution a robust and a fault tolerant one. The integrated control solution contains algorithms for the appropriate control of both the boost DC/DC converter and of the single phase inverter blocks. The proposed approaches are directed toward developing algorithms suitable for real-time implementation on 32 bit ARM processors.

  • Highly efficient thermally activated delayed fluorescence with slow reverse intersystem crossing

    摘要： We report an efficient luminescent molecule exhibiting thermally activated delayed fluorescence with a long-delayed fluorescence lifetime of 0.8 ms. Although the reverse intersystem crossing rate constant is small at 2.1 × 103 s?1, the molecule shows a high photoluminescence quantum yield of 89±2%, indicating the suppression of nonradiative decay from the triplet state.
