Nanoarchitectural Evolution from Laser-Produced Colloidal Solution: Growth of Various Complex Cadmium Hydroxide Architectures from Simple Particles

Abstract

Complex nanostructures and nanoassemblies have exhibited their potential application in the fabrication of future molecular machines and molecular devices. Liquid phase pulsed laser ablation (LP-PLA) is an easy, versatile, environmentally friendly, and rapidly growing method for the synthesis of nanostructured materials. Several experimental laser and liquid media parameters have been developed, but others are under development. The interaction of an anionic surfactant with the nanomaterials having a positive surface charge density is a key parameter, but an unanswered question until now, in the field of LP-PLA. Nanosecond pulsed laser ablation of a cadmium rod placed on the bottom of a glass vessel containing aqueous media of sodium dodecyl sulfate at different concentrations is used to produce a variety of cadmium hydroxide nanostructures from nanoparticles to nanorods, nanotetrapods, nanoflower buds, and 2D and 3D nanoflowers in order to investigate the above liquid media parameter. It is suggested tha...
