Abstract: Green and amplified spontaneous emissions with low thresholds are crucial for the development of solution‐processable perovskite light sources. Although mixed‐cation CsPbBr3 perovskites are highly promising, pinholes are inevitably formed during the spin‐coating process, which results… read more here.

Abstract: Abstract The excited-state intramolecular proton transfer molecules based on chalcone (E)-3-(4'-dimethylaminophenyl)-1-(4'-fluoro-2'-hydroxyphenyl)-2-propen-1-one (DMF-HPPO) have been synthesized under microwave irradiation. One-dimensional (1D) microwires and 2D microdisks of DMF-HPPO have been selectively prepared by controlling the solution polarity.… read more here.
