Tuning Charge‐Separated State Lifetimes in Perovskite Nanocrystal‐Perylenediimide Hybrids
Advanced Optical Materials, EarlyView.Functional perylenediimides with varied spacer lengths surface engineer CsPbBr₃ perovskite nanocrystals, yielding hybrid materials with new properties. Time‐resolved techniques reveal photoinduced charge separation from perovskite nanocrystals to perylenediimides, with microsecond‐lived charge carriers. Spacer length modulates charge carrier lifetimes,

Advanced Optical Materials, EarlyView.A unique regioselective interior/exterior borylation strategy is presented for the one‐shot synthesis of two distinct organoboron luminophores from a common macrocyclic azacalix[3]arene. This interior/exterior borylation imparts the material with remarkable TADF properties and narrowband emission capabilities, spanning the violet to blue spectral ...

The Selection of Altitude and Inclination for Remote Sensing Satellites [PDF]
Journal of Astronomy and Space Sciences, 1995 The success of a satellites mission is largely depended upon the choice of an appropriate orbit. In the case of a remote sensing satellite which observes the Earth, there exits an optimum solar elevation angle depending on the mission.

Advanced Optical Materials, EarlyView.The TTA‐UC from visible/UVA to UVB/C is demonstrated by combining a heptazine derivative with TIPS‐benzene‐based emitters. The heptazine derivative has a triplet energy level high enough to sensitize the emitters. The introduction of bulky tert‐butyl substituents to the TIPS‐benzene emitter is a simple and powerful strategy for enhancing the TTA‐UC ...

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics
Advanced Optical Materials, EarlyView.8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...
