以准球形2-金刚烷基溴化铵为唯一封端配体，在空气中制备了CH3NH3PbBr3钙钛矿纳米粒子(PAD)，其光致发光量子产率为≈100%。以葫芦醇-金刚胺(AD@CB)主客体络合物为封端配体，提高了此类纳米粒子在湿条件下的光稳定性。
CH3 NH3 PbBr3 perovskite nanoparticles (PAD) 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.
