Photoluminescence enhancement of porous silicon by organic cyano compounds
, 1998 A pronounced photoluminescence enhancement on chemically oxidized porous silicon was induced by a series of organic cyano compounds including 1,2-dicyanoethylene (CE), 1,3-dicyanobenzene (1,3-CB), 1,4-dicyanobenzene (1,4-CB), 1-cyanonaphthalene (1-CN ...

Remarks on Photoluminescence of Si Nanocrystals
It is a widely accepted opinion that the intense photoluminescence (PL) of Si nanocrystals (Si-nc) is caused by electron-hole recombination. It is also widely believed that the Auger recombination in Si-nc occurs only at collisions of one electron and ...

Anti-Stokes photoluminescence in ZnO microcrystal
, 2006 Low temperature (10 K) strong anti-Stokes photoluminescence (ASPL) of ZnO microcrystal excited by low power cw 532 nm laser is reported here. Energy upconversion of 1.1 eV is obtained in our experiment with no conventional nonlinear effect.

Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Single Crystals of Perylene Diimide‐Based Two‐Dimensional Covalent Organic Frameworks
Advanced Materials, EarlyView.Synthesizing extended crystals of two‐dimensional covalent organic frameworks (2D COFs) has remained a major challenge. Here, we report a high‐temperature double‐modulator strategy that provides access to new perylene diimide (PDI)‐based COFs with crystal sizes of up to 50 µm.
