Self-Organization of Spherical, Core-Shell Palladium Aggregates by Laser-Induced and Thermal Decomposition of [Pd(PPh3)4]

Metal in the middle: Uniform, spherical, core–shell aggregates (100±20 nm; see picture) are obtained by photodecomposition of [Pd(PPh3)4] to form the metal core, followed by aggregation of smaller Pd nanocrystals and free phosphanes, produced by thermal decomposition of the remaining precursor, arou...

Description
Summary:Metal in the middle: Uniform, spherical, core–shell aggregates (100±20 nm; see picture) are obtained by photodecomposition of [Pd(PPh3)4] to form the metal core, followed by aggregation of smaller Pd nanocrystals and free phosphanes, produced by thermal decomposition of the remaining precursor, around this core. Prolonged irradiation or thermal decomposition alone yields only the core structure or the shell structure, respectively. This enables the nanoparticle structure to be tuned.
