Abstract

For the first time, polystyrene sulfonic acid solution (PSS) was observed to emit blue fluorescence. The photoluminescence (PL) behavior of PSS under different concentrations, pH values and magnetic field strengths was investigated, revealing the diversity and tunability of its PL properties. PSS possesses remarkable down-conversion properties and strong responsiveness to external magnetic fields.
