Abstract

When laser irradiation for colloidal materials is conducted, fragmentation of the materials is induced by the laser energy adsorbed by the materials. It has become well-known that this phenomenon (laser fragmentation, LF) is indispensable for nanomaterial synthesis, particularly because of the simplicity of the procedure. This chapter introduces fundamental aspects of LF of nanoparticles (NPs) of noble metals. Many earlier works have shown that LF is quite useful to reduce the nanoparticle size. Nanoparticle size control is also possible by adjusting simple experimental conditions such as laser intensity and the use of stabilizers. Additionally, the LF mechanism has been investigated quantitatively because the optical properties of noble metal NPs are well-defined. Consequently, LF of NPs is not only an important method for nanomaterials synthesis, it is also an ideal model for investigating laser–material interaction.
