Abstract

An efficient synthesis of highly crystalline SnO₂ QDs with a narrow size distribution (4.27 ± 0.67 nm) was achieved by microwave-assisted decomposition of Sn(OtBu)₄ in ionic liquid. Printed structures fabricated from SnO₂ QDs showed typical semiconducting I–V behaviors, and gas sensing properties.
