Zinc-halide/phenylbutyrate co-passivation of CsPbX nanocrystals toward efficient and robust luminescence.

Cesium lead halide perovskite nanocrystals (IPNCs) exhibit excellent optoelectronic properties but are susceptible to degradation in practical environments due to their ionic surface and unstable ligand capping. Here, we propose a post-synthesis surface passivation strategy for CsPbX (X = Br, I) IPNCs by employing combined zinc halide and zinc phenylbutyrate (Zn(PA)) as surface ligands. ZnBr fills surface halide vacancies on IPNCs, resulting in high photoluminescence efficiency, whereas Zn(PA) stabilizes IPNCs by substituting surface ammonium ligands.

Aluminum Carboxylate Modification Enabled Efficient and Stable Perovskite-Polystyrene Thin Films for Light-Emitting Applications.

Lead halide perovskite nanocrystals (PNCs) have demonstrated great potential in emerging display technologies. However, the practical application of PNCs is hindered by the inherent instability of their ionic surface. Here, we proposed a surface modification approach to enhance the stability of CsPbBr PNCs by postsynthetic treatment with aluminum phenylbutyrate (Al(PA)).

[Effects of different cultivation patterns on soil aggregates and organic carbon fractions].

Combined with the research in an organic farm in the past 10 years, differences of soil aggregates composition, distribution and organic carbon fractions between organic and conventional cultivation were studied by simultaneous sampling analysis. The results showed that the percentages of aggregates (> 1 mm, 1-0.5 mm, 0.
