Researchers create perovskite quantum dot microarrays for improved displays

Researchers from the Beijing Institute of Technology and MIIT Key Laboratory for Low Dimensional Quantum Structure and Devices have developed perovskite quantum dots microarrays with strong potential for quantum dots color conversion (QDCC) applications, including photonics integration, micro-LEDs, and near-field displays.

QDCC is considered a versatile way to achieve full-color organic light-emitting diodes and micro-light-emitting diodes displays. QDCC provides a wide range of color performance and easy integration. However, conventional QDCC pixels, fabricated by the commonly used method of inkjet printing, tend to be too thin to achieve efficient color conversion. The conventional combination of quantum dots and coffee-ring effects or puddle of particle-laden liquid that occur after evaporation, lowers the light conversion efficiency and emission uniformity in quantum dot microarrays. This also contributes to blue-light leakage or optical crosstalk, where unwanted coupling occurs between signal paths.

Applications of perovskite materials in the display industry

This article was extracted from the Perovskite for Displays market report.

Given perovskites materials' unique optical properties, these materials are being intensively researched for both photovoltaic and display applications (as well as several others). In this article we will take a look into the possible application areas in the display industry that can benefit from perovskite materials.

Perovskite QDs

Perovskite-based QDs (PerQDs) are considered a viable Cd-free alternative for display applications, with high PL quantum yields, wide wavelength tunability and ultra-narrow band emission. The main advantages of PerQDs are:

  • Low cost
  • High performance
  • RoHS compliance (despite the lead content)

Tip-induced strain engineering of single metal halide perovskite quantum dots

A joint research team, affiliated with Korea's UNIST, has developed a novel method capable of controlling the brightness and wavelength of quantum dots (QDs). The work was led by Professor Kyoung-Duck Park in the Department of Physics at UNIST, in collaboration with Professor Sohee Jeong in the Department of Energy Science from Sungkyunkwan University (SKKU).

The research team demonstrated the tip-induced dynamic control of strain, bandgap, and quantum yield of single CsPbBrxI3'x pQDs by using a controllable plasmonic nanocavity combined with tip-enhanced photoluminescence (TEPL) spectroscopy.
