Lithographic in-mold patterning for CsPbBr₃ nanocrystals distributed Bragg reflector single-mode laser

Abstract

Extensive studies on lead halide perovskites have shown that these materials are excellent candidates as gain mediums. Recently, many efforts have been made to incorporate perovskite lasers in integrated optical...

Integration of on-chip perovskite nanocrystal laser and long-range surface plasmon polariton waveguide with etching-free process

“…After that, the sample was dried in a vacuum for 24 hours (Step 5). 15 The synthesis of the CsPbBr 3 NCs followed previous literature. 13 Finally, a lift-off process was performed in ethyl acetate solution on the dried sample to remove the photoresist and reveal the CsPbBr 3 cavity (Step 6).…”

“…11,12 The fabricated perovskite lasers exhibit low lasing thresholds, large-quality factors, single-mode lasing behavior, and wavelength tunability in the visible light region. 13–17…”

Laser Technology for Perovskite: Fabrication and Applications

“…[81,82] The laser treatment can be employed for cut-ting, drilling, etching, and modifying surfaces to achieve precise control and processing of perovskites. [83,84] Konidakis et al synthesized CH 3 NH 3 PbI 3 perovskite thin films via laser-assisted (LA) thermal annealing crystallization on the surface of two HTLs: poly(3,4-ethylenedioxythiophene)-poly(styrene-sulfonate) (PEDOT:PSS) and poly(triarylamine) (PTAA) (Figure 6a). [85] For the PEDOT:PSS/CH 3 NH 3 PbI 3 structures, the laser processing led to the formation of larger grains, enhancing the charge carrier extraction properties and reducing the bimolecular recombination rate within the perovskite layers (Figure 6b).…”

Micropore filling fabrication of high resolution patterned PQDs with a pixel size less than 5 μm

“…31,32 Because of the lack of suitable photoresists for PQDs, only a few works have achieved dual color QD patterns with the pixel size less than 10 μm for micro-LED based augmented reality (AR) display applications. 33,34…”
