Abstract

The technique of laser ablation in liquids (LAL) has already demonstrated its flexibility and capability for the synthesis of a large variety of surfactant-free nanomaterials with high purity [1]. However, high purity can cause trouble for nanomaterial synthesis because active high-purity particles can spontaneously grow into different nanocrys-tals [2], which makes it difficult to accurately tailor the size and shape of the synthesized nanomaterials. Therefore, a series of questions arise in regard to whether particle growth occurs during colloid storage, how large the particle size increases to, and which shape the particles evolve into.
