Chemi-Structural Stabilization of Formamidinium Lead Iodide Perovskite by Using Embedded Quantum Dots
American Chemical Society (2020-01-6)The approaches to stabilize the perovskite structure of formamidinium lead iodide (FAPI) commonly result in a blue shift of the band gap, which limits the maximum photoconversion efficiency. Here, we report the use of PbS ... -
Directional and Polarized Lasing Action on Pb-free FASnI3 Integrated in Flexible Optical Waveguide
(2022)In this work, high-quality FASnI3 (FA, formamidinium) lead-free perovskite thin films are successfully incorporated in a flexible polyethylene terephthalate (PET) substrate to demonstrate amplified spontaneous emission ... -
Enhancing the Electronic Properties and Stability of High-EfficiencyTin-Lead Mixed Halide Perovskite Solar Cells via DopingEngineering
American Chemical Society (2022-03-31)Overcoming Voc loss to increase the efficiency of perovskite solar cells (PSCs) has been aggressively studied. In this work, we introduce and compare rubidium iodide (RbI) and potassium iodide (KI) alkali metal halides ... -
Lead-Free Halide Perovskite Materials and Optoelectronic Devices: Progress and Prospective
Wiley (2023)Halide perovskites, in the form of thin films and colloidal nanocrystals, have recently taken semiconductor optoelectronics research by storm, and have emerged as promising candidates for high-performance solar cells, ... -
Single-Exciton Amplified Spontaneous Emission in Thin Films of CsPbX3 (X = Br, I) Perovskite Nanocrystals
American Chemical Society (2019-09-23)CsPbX3 perovskite nanocrystals (PNCs) have emerged as an excellent material for stimulated emission purposes, with even more prospective applications than conventional colloidal quantum dots. However, a better understanding ... -
Suppressing the Formation of High n-Phase and 3D Perovskites in the Fabrication of Ruddlesden-Popper Perovskite Thin Films by Bulky Organic Cation Engineering
American Chemical Society (2022-02-24)Two-dimensional perovskites (2D PVKs) were first studied because of their dielectric and magnetic properties for dielectric and transistor applications in the electronic field. As the optical properties were elucidated ... -
Unusual Spectrally Reproducible and High Q-Factor Random Lasing in Polycrystalline Tin Perovskite Films
Wiley (2022)An unusual spectrally reproducible near-IR random lasing (RL) with no fluctuation of lasing peak wavelength is disclosed in polycrystalline films of formamidinium tin triiodide perovskite, which have been chemically ...
