Abstract
Nanoparticle has pulled in expanding consideration with the developing enthusiasm for nanotechnology which hold potential as essential segments for development applications. In the present work, a copper nanoparticle is manufactured as a suspension in distilled water by beating a bulk copper target with laser source (532 nm wavelength, 10 ns pulse duration and 10 Hz repletion rate) via method. UV- visible absorption spectra and AFM analysis has been done to observe the effect of repetition rate for the pulsation of laser. Copper nanoparticles (Cu-NPs) were successfully synthesized with green color. The Cu- NPs have very high purity because the preparation was managed in aqueous media to eliminate ambient contaminations. Absorption spectrum shows peaks at 450 nm- 700 nm µm due to the generation of Cu-NPs.
Highlights
Synthesis of nanoparticles with controlled geometry and size is an interesting scientific field
There is no exclusive definition for nanoparticles; those particles are defined with size less than 100 nm, where the physical properties of the material turn out to be so unique
What's more, optical properties can be gotten in such nanoparticles which has interesting applications with regards to technology innovations
Summary
Synthesis of nanoparticles with controlled geometry and size is an interesting scientific field. There is no exclusive definition for nanoparticles; those particles are defined with size less than 100 nm, where the physical properties of the material turn out to be so unique. Because of the imprisonment impact of the fluid, these catapulted species structure a thick district in the region of the solid– fluid interface This stage is like that happens in a vacuum or low weight gas, where the laser creates a plasma plum. The plasma extends adiabatically at supersonic speed, making reflection and discharging of the shockwave started by the plasma weight from the back and front surfaces of the solid target. This stun wave incites an additional, immediate weight as it goes through the fluid.
