Abstract
AbstractHollow spheres and a honeycomb‐like macroporous framework structure of InP have been successfully fabricated by employing Au/In core/shell composite colloid droplets formed in situ as the template and catalyst for a simple analogous solution‐liquid‐solid (ASLS) growth route. SEM images show that the morphology of the obtained InP is mostly micrometer‐scale hollow spheres (>80 %) accreted with honeycomb‐like structures (<5 %). These hollow spheres have well‐defined voids and homogeneous walls, and the surface of the obtained InP hollow spheres is porous, which indicates that the building blocks are InP nanoparticles formed by solidification on the surface of Au/In core/shell droplets. A possible growth mechanism for the micrometer hollow spheres and honeycomb‐like macroporous framework is proposed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
