Self-Assembly and Regrowth of Metal Halide Perovskite Nanocrystals for Optoelectronic Applications

Jiakai Liu et al.

Summary: The self-assembly and regrowth of metal halide perovskite (MHP) nanocrystals have attracted significant attention due to their potential applications in photovoltaics, X-ray scintillators, and LEDs. Through self-assembly and regrowth, the structure and morphology of MHP nanocrystals can be controlled, leading to improved commercial potential. Additionally, the self-assembly and regrowth processes can modify the electronic properties of MHP nanocrystals, resulting in enhanced device performance. However, further research is needed to fully understand the design principles and applications of MHP self-assembly and regrowth.

Solution-Processed Efficient Perovskite Nanocrystal Light-Emitting Device Utilizing Doped Hole Transport Layer

Xinyu Shen et al.

Summary: The all-solution process for inorganic perovskite nanocrystals (PNCs) LEDs shows great potential for new-generation illumination and displays, but the challenge lies in the injection barriers and charge injection imbalance. The introduction of CBP into the hole transport layer (HTL) efficiently modulates the charge carrier mobility and energy level, resulting in barrier-free charge injection and optimal performance for solution-processed PNC LEDs. The luminance of red LEDs reaches 2990 cd m(-2) and the external quantum efficiency achieves 8.1%, with improved turn-on voltage and roll-off due to more balanced charge injection.

Ligand-assisted solid phase synthesis of mixed-halide perovskite nanocrystals for color-pure and efficient electroluminescence

Simon F. Solari et al.

Summary: A new post-synthetic approach of ligand-assisted solid phase synthesis (LASPS) has been demonstrated for the preparation of electroluminescent colloidal nanocrystals (NCs) of lead halide perovskites of methylammonium (MA) at room temperature, showing emission covering the entire visible spectral region. The resulting NCs have photoluminescence (PL) quantum yields (QYs) of up to >90% and colloidal stability up to several months. LEDs fabricated using the prepared mixed-halide NCs display narrowband electroluminescence (EL) ranging from 476 to 720 nm.
