3D perovskites, quasi-2D perovskites, and perovskite nanocrystals) are commonly included in the emitter layer of PeLEDs12,13,14,15,16. 3D PeLEDs have achieved EQEs of more than 20% in both the near
Fabrication of 2D perovskite layers on 3D perovskite light absorbers, as the perovskite solar cells (PSCs), is being exploited to achieve a high power-conversion efficiency (PCE) along with promising long-term stability. However, to improve the performance of PSCs, an intermediate layer of smart...
Note that, achieving high-quality, pinhole-free perovskite films with uniform coverage and minimal defect density on various semiconducting channel materials, including Si, remains a formidable challenge9. In this context, the recent breakthrough in hybrid MBE on the synthesis of freestanding10 single...
The high stability of the two-dimensional (2D) perovskite structure can be ascribed to its long-chain organic molecules. In this study, the thermal assisted blade coating method was used to prepare high-quality and pinhole-free perovskite film. We prepared 2D perovskite solutions and fabricated ...

Perovskite films have emerged as candidates for light-emitting diodes on accounts of excellent optical properties and low cost. Construction of quasi-2D perovskite films by incorporating organic ammonium is an effective method to manufacture a pinhole-free film with high photoluminescence quantum yield (...
The thermal energy of the preheated substrate facilitates not only the growth of a continuous and pinhole-free perovskite film, but also the formation of a highly crystalline and preferentially oriented perovskite structure, resulting in improved luminescence properties. Therefore, PeLEDs fabricated using...
