Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption
Advanced Functional Materials, EarlyView.Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

Accuracy of Solar Eclipse Calculation Algorithm Based on Jet Propulsion Laboratory Data Nasa
Al-Ahkam, 2020 DE200 and DE405 are Development Ephemeris (DE) series released by the National Aeronautics and Space Administration (NASA) in 1981 and 1997. NASA uses DE405 to predict solar eclipses in 2011-2020.

The ionospheric responses to the 11 August 1999 solar eclipse: observations and modeling [PDF]
Annales Geophysicae, 2008 A total eclipse occurred on 11 August 1999 with its path of totality passing over central Europe in the latitude range 40°–50° N. The ionospheric responses to this eclipse were measured by a wide ionosonde network.

Exciton Dynamics in Layered Halide Perovskite Light‐Emitting Diodes
Advanced Materials, EarlyView.This review discusses the exciton dynamics in layered halide perovskitelight‐emitting diodes (PeLEDs). It opens with a summary of the structural and photophysical aspects, followed by an exploration of controlling dimensionality and cascade exciton transfer in quasi‐2D PeLEDs.

Advanced Materials Interfaces, EarlyView.The photophysical properties of a hybrid solid state film, composed of a conjugated polymer and CsPbBr3 (zwitterionic sulfobetaine ‐capped) perovskite nanocrystals (NCs), are investigated by ultrafast spectroscopy and morphological characterization. The transient spectroscopy highlights the presence at the interface of a charge transfer state, and the ...
