Gold nanoclusters based dual-emission hollow TiO 2 microsphere for ratiometric optical thermometry

Wang, Chuanxi; Huang, Yijun; Lin, Huihui; Xu, Zhenzhu; Wu, Jiapeng; Zhang, Chi; Humphrey, Mark


In this work, we develop a novel dual-emitting hollow TiO<inf>2</inf> microsphere with high stability and attractive thermal sensitivity, which could work as nanosensor for accurately measuring temperature. This nanosensor is prepared through coating gold nanocluster (AuNCs) on the surface of carbon dots-doped hollow TiO<inf>2</inf> microsphere. As-prepared nanosensor shows characteristic dual-emitting property of carbon dots (CDs, blue fluorescence) and AuNCs (red fluorescence) under a single...[Show more]
