Introducing ytterbium acetate to luminescent CsPbCl3 nanocrystals for enhanced sensitivity of Cu2+ detection

The Yb(OAc) 3 promoted the formation of CsPbCl 3 nanowires (NWs). The NWs exhibited boost in conductivity and the adsorbed AcO − on the surface of NWs enhanced the adsorption capacity of Cu 2+ , which enabled NWs with high detection sensitivity of Cu 2+ .
