2019 MRS Fall Meeting & Exhibit

Symposium EN10-Emerging Light-Emitting Materials and Devices—Perovskite Emitters, Quantum Dots and Other Low-Dimensional Nanoscale Emitters

Major research goals of self-emissive materials for displays and optoelectronics have revolved around high luminescence efficiency and long device lifetime. To overcome the issues of conventional organic fluorescent and phosphorescent emitters in terms of suboptimal color purity and high material cost, new classes of light emitters such as organic-inorganic hybrids, halide perovskites, and inorganic semiconductor nanocrystals and other low-dimensional structures, amorphous and polycrystal films are increasingly proposed for displays, lightings, lasers, and other optoelectronic applications beyond solar cells. In particular, metal halide perovskite emitters are emerging as strong contenders in the arena of narrow-band and low-cost emitters for high color-purity light sources.
This symposium will be dedicated to the synthesis, photophysics and devices comprising emerging light emitting materials. We plan to dedicate at least four sessions of the proposed symposium to the novel classes of light-emitting materials (one for synthesis of halide perovskite and perovskite-like emitters, one for characterization of halide perovskite emitters, another is for synthesis inorganic nanoscale emitters, and another will focus on other low-dimensional emitters). It is also planned to dedicate one session to photophysics of the emerging emitting materials. Applications of these materials to optoelectronic devices are also important parts of symposium. Accordingly, it is also planned to dedicate another session to device physics. While reports on metal halide perovskites will be particularly encouraged, outstanding achievements from the most recently research in other carbon and inorganic nanoscale materials will also be the topics in two sessions. Besides electroluminescence, materials for down-conversion emission and stimulated emission (laser) will also be covered. Therefore, the symposium will cover the complete range from the synthesis and characterization of emerging emitting materials to their fundamental chemistry and physics, and related practical device applications.
This symposium will be highly interdisciplinary. Speakers from chemistry, physics, materials science and other related engineering fields will discuss cutting-edge progress on theoretical and experimental work. The discussions are expected to accelerate the development of the emerging materials and devices toward practical applications.

Topics will include:

  • Emerging organic-inorganic hybrid and halide perovskite emitters
  • Emerging inorganic or carbon-based nanoscale emitters
  • Nanowire, quantum dot, 2D materials and point defect emitters
  • Scalable processing of emitters
  • Photophysics (excitation, recombination, photo- and electroluminescence) of emitters
  • New device architecture for light-emitting diodes
  • Charge transport layers and interfacial effects in light-emitting diodes
  • Down-conversion emitters and devices
  • Lasing from micro- and nanoscale materials
  • Materials emitting out of the visible wavelengths (deep UV, near-infrared)
  • Other optoelectronic devices for light emitting applications
  • A tutorial complementing this symposium is tentatively planned.
