Abstract

A simple and feasible approach was constructed for preparation of all inorganic cesium lead bromide perovskite nanocrystals (CsPbBr3 NCs) modified with tetraphenylporphyrin tetrasulfonic acid (TPPS). The CsPbBr3/TPPS nanocomposite has good water stability and exhibits a dual-emission property. Adopting the CsPbBr3/TPPS nanocomposite as a nanoprobe, a rapid, selective and sensitive ratiometric fluorescent method was developed for determination of sulfide ion. When sulfide ion was added into the CsPbBr3/TPPS nanocomposite, the bright green fluorescence of CsPbBr3 NCs at 520 nm was sharply quenched, whereas the red fluorescence of TPPS at 650 nm was hardly influenced. The quenching is possibly attributed to destruction of CsPbBr3 NCs via the formation of more stable PbS. This nanoprobe can determine sulfide ion over the range of 0.2–15.0 nmol·L−1 with a detection limit as low as 0.05 nmol·L−1. The relative standard deviation is 3.3% at 10.0 nmol·L−1 concentration level (n = 11). Sulfide ion content was successfully determined in different water samples by this nanoprobe.
