Abstract

CH NH PbBr perovskite nanoparticles (P ) are prepared with a photoluminescence quantum yield of ≈100% in air atmosphere by using the quasi-spherical shaped 2-adamantylammonium bromide (ADBr) as the only capping ligand. The photostability under wet conditions of this kind of nanoparticles is enhanced by using cucurbit[7]uril-adamantylammonium (AD@CB) host-guest complexes as the capping ligand.

摘要

CH NH PbBr 钙钛矿纳米粒子（P）通过使用准球形的 2-金刚烷基溴化铵（ADBr）作为唯一的封端配体，在空气气氛中以约 100%的光致发光量子产率制备。通过使用葫芦[7]脲-金刚烷基铵（AD@CB）主客体配合物作为封端配体，这种纳米粒子在潮湿条件下的光稳定性得到增强。
