Gold Nano Particles- An Overview!

The gold Nano particles have been put to use for centuries by scientists because of vibrant colors formulated by their interaction and visible light. The electronic along with optical properties of Gold Nano rods could be altered by changing their size, surface area or state of aggression.
Electrical along with optical properties of Gold Nano rods
The interaction of light by Gold Nano rods is strongly discouraged by their surface area, size in consortium with dimensions. Once the size of the particle is known to increase towards the bulk limit, the reasonable wave lengths do move over to the IR portion of the spectrum.
This is a phenomenon that is seen when excess salt is added to the gold particles. Then the surface charge of the gold particle becomes neutral. Because of this the solution goes on to change color from...
