Title: Electrochemical Lithium Doping Induced Property Changes In Halide Perovskite CsPbBr₃ Crystal

Abstract

Electrochemical doping was used to dope lithium into perovskite CsPbBr₃ crystal. Due to the doping, diamagnetic behavior was observed with a transition temperature (T_c) of 7.17 K. Burstein-Moss effect related photoluminescence (PL) blue-shift was observed as long as 15 nm. UV-vis-NIR spectra indicate that the absorption has been enhanced. As a result, the doped CsPbBr₃ crystal generated 8 nA photocurrent, which is higher than the undoped CsPbBr₃ crystal.

CsPbBr₃ Perovskite Nanocrystal Grown on MXene Nanosheets for Enhanced Photoelectric Detection and Photocatalytic CO₂ Reduction

Journal Article Pan, Aizhao ; Ma, Xiaoqin ; Huang, Shengying ; ... - Journal of Physical Chemistry Letters

All-inorganic CsPbX₃ (X = Cl, Br or I) perovskite nanocrystals have attracted extensive interest recently due to their exceptional optoelectronic properties. In an effort to improve the charge separation and transfer following efficient exciton generation in such nanocrystals, novel functional nanocomposites were synthesized by the in situ growth of CsPbBr₃ perovskite nanocrystals on two-dimensional MXene nanosheets. Efficient excited state charge transfer occurs between CsPbBr₃ NCs and MXene nanosheets, as indicated by significant photoluminescence (PL) quenching and much shorter PL decay lifetimes compared with pure CsPbBr₃ NCs. The as-obtained CsPbBr₃/MXene nanocomposites demonstrated increased photocurrent generation in response to visible light andmore »« less

In situ synthesis and macroscale alignment of CsPbBr₃ perovskite nanorods in a polymer matrix

Journal Article He, Juan ; Towers, Andrew ; Wang, Yanan ; ... - Nanoscale

Here, we report an in situ catalyst-free strategy to synthesize inorganic CsPbBr₃ perovskite nanorods in a polymer matrix (NRs-PM) with good dimensional control, outstanding optical properties and ultrahigh environmental stability. Polarization photoluminescence (PL) imaging with high spatial resolution was carried out for the first time on single nanorod (NR) and shows a relatively high local polarization ratio (~0.4) consistent with theoretical predictions based on a dielectric contrast model. We further demonstrate that macroscale alignment of the CsPbBr₃ nanorods can be achieved through mechanically stretching the NRs-PM films at elevated temperature, without deteriorating the optical quality of the NRs.

Enhanced Size Selection in Two-Photon Excitation for CsPbBr₃ Perovskite Nanocrystals

Journal Article Chen, Junsheng ; Chabera, Pavel ; Pascher, Torbjorn ; ... - Journal of Physical Chemistry Letters

Here, cesium lead bromide (CsPbBr₃) perovskite nanocrystals (NCs), with large two-photon absorption (TPA) cross-section and bright photoluminescence (PL), have been demonstrated as stable two-photon-pumped lasing medium. With two-photon excitation, red-shifted PL spectrum and increased PL lifetime is observed compared with one-photon excitation. We have investigated the origin of such difference using time-resolved laser spectroscopies. We ascribe the difference to the enhanced size selection of NCs by two-photon excitation. Because of inherent nonlinearity, the size dependence of absorption cross-section under TPA is stronger. Consequently, larger size NCs are preferably excited, leading to longer excited-state lifetime and red-shifted PL emission. In amore »« less

Ultrathin Colloidal Cesium Lead Halide Perovskite Nanowires

Journal Article Zhang, Dandan ; Yu, Yi ; Bekenstein, Yehonadav ; ... - Journal of the American Chemical Society

Highly uniform single crystal ultrathin CsPbBr₃ nanowires (NWs) with diameter of 2.2 ± 0.2 nm and length up to several microns were successfully synthesized and purified using a catalyst-free colloidal synthesis method followed by a stepwise purification strategy. The NWs have bright photoluminescence (PL) with a photoluminescence quantum yield (PLQY) of about 30% after surface treatment. Large blue-shifted UV-vis absorption and PL spectra have been observed due to strong two-dimensional quantum confinement effects. A small angle X-ray scattering (SAXS) pattern shows the periodic packing of the ultrathin NWs along the radial direction, demonstrates the narrow radial distribution of the wires,more »« less

Efficient conversion from UV light to near-IR emission in Yb{sup 3+}-doped triple-layered perovskite CaLaNb{sub 3}O{sub 10}

Journal Article Lu, Yuting ; Li, Yuze ; Qin, Lin ; ... - Materials Research Bulletin

Graphical abstract: CaRNb{sub 3}O{sub 10} is a self-activated oxide due to charge transfer transition in octahedral NbO{sub 6} groups. CaLaNb{sub 3}O{sub 10}:Yb{sup 3+} presents intense IR emission due to the cooperative energy transfer from host (NbO{sub 6}) to Yb{sup 3+} is responsible. It could be expected to be potentially applicable for enhancing photovoltaic conversion efficiency of Si-based solar cells. - Abstract: Yb{sup 3+}-doped triple-layered perovskite CaLaNb{sub 3}O{sub 10} micro-particles were synthesized via the solid-state reaction method. The crystal structure and morphology of the polycrystalline samples were investigated by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) measurements, respectively.
