Synthesis of monodispersed Au–PbS hybrid nanocrystals via a solid–liquid interfacial reaction

Abstract

A facile solid–liquid interfacial synthetic strategy has been developed to synthesize Au–PbS hybrid nanocrystals via a thermolysis process. The size of the obtained Au–PbS hybrid nanocrystals could be tuned by varying the amounts of HAuCl4 introduced into the reaction system. A mutual inhibition of particle growth for both components in the hybrid nanocrystals has been observed during the synthetic process.
