Microwave assisted fast and facile synthesis of SnO2 quantum dots and their printing applications

Abstract

An efficient synthesis of highly crystalline SnO(2) 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 SnO(2) QDs showed typical semiconducting I-V behaviors, and gas sensing properties.
