Modulated oxygen vacancies in europia clusters/black phosphorus induced signal amplification for efficient chemiluminescence sensing

Abstract

In this work, we proposed an oxygen vacancy engineering strategy to boost the chemiluminescence (CL) efficiency in europia clusters/black phosphorus quantum dots (Eu₂O₃/BPQDs), which could dramatically amplify the ClO⁻ CL emission through electron transfer. Accordingly, a sensitive and direct CL sensing platform for hypochlorite and titanium ions was constructed. This work provides a neoteric methodology by modulating the surface state of nanoparticles to boost the CL sensitivity.
