Role of reactant concentration and identity of added cation in controlling emission from post-synthetically modified terbium incorporated zinc sulfide nanoparticles: an avenue for the detection of lead(ii) cations.

ABSTRACT: This work reports the photophysical properties of 1-thioglycerol capped hydrophilic terbium cation incorporated (doped) zinc sulfide [Zn(Tb)S] nanoparticles, which have been post-synthetically modified using Pb²⁺ [Zn(Tb)S/Pb] under ambient conditions with [Zn(Tb)S] : [Pb²⁺] = 1 : 10^-5-1 : 10, essentially providing a scenario with low to heavy co-doping and ultimately the possibility of forming a material of different chemical identity. The effects of selected concentrations of [Zn(Tb)S] : [M ⁿ⁺] = 1 : 1 and 1 : 10^-2 have also been evaluated for the post-synthetic addition of Hg²⁺, Cd²⁺, Ca²⁺, Mg²⁺, Na⁺ and K⁺.
