Tuning Surface Plasmon Resonance Of Au Nanoparticles Within A Diamond Anvil Cell Under High Pressure

Related work of the paper studied the spectra of the gold nanoparticles solution under high-pressure environment regulation of the subject.Which made us deeply understand the nature of the nanometer gold particles under high pressure, especially the mechanical properties of dynamic balance between the gold particles, the more close to its essential factor affecting the spectral changes.The subject of research, broadening the research field of the high pressure science provides us with a new train of thought to research the basic nature of matter, and you can let us more in-depth research more material to form under high pressure.Under high refractive index and pressure changes implemented using the solution of the transmission spectrum of gold nanoparticles solution control.Research obtained with the change of the pressure of the gold nanoparticles solution absorption peak depends on the solution of the linear refractive index this relationship.Finally we can think of a specific size of the gold nanoparticles solution or permits accurate prediction under 1.2 GPa absorption fengfeng a relationship between the pressure curve of the slope.Success as a result OF this work.Y.

Lett.107,201909 (2015).Under the environment of high voltage electrostatic repulsion between the gold nanoparticles and its surface ligands of interaction, van der Waals force control solution of variable parameter, realize the self-assembly of particles, and therefore can regulate its absorption spectrum. Work to establish a set of perfect high-pressure self-assembly theory system, and be able to justify high pressure experiment, formed a set of self consistent system. Submit work is under way.To sum up, the above work from three aspects respectively around the gold nanoparticles achieved in high pressure environment on the regulation of the spectrum.
