You can measure particle size by SEM or TEM. Also crystallite size can be calculated by XRD using Scherrer equation.
Dear Khalid,
A common method is the dynamic light scattering. A device that use this method is the Zetasizer Nano Range from Malvern. I've used it several times and it gave me great results, oderwise it is a sensitive device and may be well calibrated and the sample well prepared.
Best regards!
Hi Khalid
You can use TEM or XRD as Shankar said. TEM is a powerful tool to measure particles in nanoscale. You need to report your TEM results as a histogram of particle size distribution.

Besides above mentioned XRD,TEM,SEM, the ditribution of the particles can be measured by laser diffraction particle size analysis.
You can get results of particle size by Zetasizer, but if you want images of your particle with their sizes go for TEM.
High power CO2 lasers are suitable for surface treatment , welding, and cutting
There are several methods as mentioned already. The best method is High Resolution TEM. However, the sample preparation is most important in TEM investigation. The nanoparticles have a tendency to agglomerate, therefore the powder particles should be well dispersed before characterization.
Good Luck.
Definitely
Scanning Mobility Particle Sizer Spectrometer (SMPS).
It can classify monodisperse nanoparticles or scan the size distribution from several to several hundreds nanometers.
Nice suggestions have been added to the question.
SEM and TEM are the most suitable techniques to study the particle size and distribution.
