The Deepest Blue: Major Advances and Challenges in Deep Blue Emitting Quasi‐2D and Nanocrystalline Perovskite LEDs
Year: 2024
Type: article
Abstract: In this review, the recent development of blue perovskite light-emitting diodes (PeLED) are summarized. On deep-blue (≤465 nm) perovskite nanomaterials of different structural forms are mainly focused, including nanocrystals (NCs), quantum dots (QDs), nanoplatelets (NPLs), quasi-2D thin film, 3D bulk thin film, as well as lead-free perovskite nanomaterials. The current challenges are also examined in producing efficient deep-blue PeLED, such as material and spectral instability, imbalance charge transport, Joule heat impact, and poor optoelectronic performance. Several strategies are further discussed to overcome these challenges and achieve efficient deep-blue PeLED for next-generation display technology.
