Abstract

The observation of photoluminescence (PL) enhancement and quenching for 580 nm emission following the variation of time decay patterns, induced by Zn²⁺ and Mn²⁺, respectively were reported. The analysis of activation and quenching processes was done by considering surface nonradiative relaxation based on the Langmuir isotherm and Poisson statistics, respectively. It was observed that the PL enhancement was related to the elimination of dangling bonds from the lone pairs on surface S^2- anions. It was found that the rich Zn²⁺ and poor Mn²⁺ in colloidal ZnS:Mn²⁺ nanoparticles were the key to obtain highly efficient luminescence.
