Special Issue Information

Dear Colleagues,

The emerging perovskite-based nanodevices have received remarkable research interest due to their outstanding optoelectronic characteristics. Perovskite-based nanostructures (e.g., waveguide, metamaterial, metasurface) and nanodevices (photovoltaic, light emitting diode, photodetector, laser, memristor, etc.) have become topics of interest and been intensively studied. However, there are several challenges, such as the underlying working mechanisms, fabrication recipes, long-term stability, and toxicity, which substantially hinder the delivery of highly efficient perovskite-based nanostructures and nanodevices.

This Special Issue of Nanomaterials welcomes contributions of original research articles, reviews, perspectives, and comments concerning the challenges faced in the research area of perovskite-based nanostructures and nanodevices. The topics include the synthesis of new perovskites with versatile (inorganic) material composition and engineering of (0D, 1D, 2D and 3D) perovskite nanostructures such as waveguide, metamaterial, and metasurfaces. This also includes research work that contributes to the development of high-efficiency perovskite-based nanodevices such as photovoltaic, light-emitting diodes, photodetectors, lasers, memristors, etc., as well as theoretical and experimental understanding to unveil the working mechanisms. Beyond the above topics, other original research closely related to perovskite-based nanostructures and nanodevices is also highly welcome.

Abstract

In this work, we studied, at low temperature, the coherent evolution of the localized electron and hole spins in a polycrystalline film of CH₃NH₃PbI₃ (MAPI) by using a picosecond-photo-induced Faraday rotation technique in an oblique magnetic field. We observed an unexpected anisotropy for the electron and hole spin. We determined the electron and hole Landé factors when the magnetic field was applied in the plane of the film and perpendicular to the exciting light, denoted as transverse

⊥

factors, and when the magnetic field was applied perpendicular to the film and parallel to the exciting light, denoted as parallel

∥

factors. We obtained

| g_{e, ⊥} | = 2.600 \pm 0.004

| g_{e, ∥} | = 1.604 \pm 0.033

for the electron and

| g_{h, ⊥} | = 0.406 \pm 0.002

| g_{h, ∥} | = 0.299 \pm 0.007

for the hole. Possible origins of this anisotropy are discussed herein. Full article

Abstract

Nowadays, Mn-doping is considered as a promising dissolution for the heavy usage of toxic lead in CsPbX₃ perovskite material. Interestingly, Mn-doping also introduces an additional photoluminescence band, which is favorable to enrich the emission gamut of this cesium lead halide. Here, a solution spraying strategy was employed for the direct preparation of CsPb_xMn_1−x(Br,Cl)₃ film through MnCl₂ doping in host CsPbBr₃ material. The possible fabrication mechanism of the provided approach and the dependences of material properties on Mn-doping were investigated in detail. As the results shown, Pb was partially substituted by Mn as expected. With the ratio of PbBr₂:MnCl₂ increasing from 3:0 to 1:1, the obtained film separately featured green, cyan, orange-red and pink-red emission, which was caused by the energy transferring process. Moreover, the combining energy of Cs, Pb, and Mn gradually red-shifted resulted from the formation of Cs-Cl, Pb-Cl and Mn-Br coordination bonding as MnCl₂ doping increased. In addition, the weight of short decay lifetime of prepared samples increased with the doping rising, which indicated a better exciton emission and less defect-related transition. The aiming of current work is to provide a new possibility for the facile preparation of Mn-doping CsPbX₃ film material. Full article
