Nano particle materials are tested by following techiques:

SEM and TEM (size and morphology )

EDs(mapping of elemental dispersion)

XRD (crystal structure, crystallite size..)

TGA/DSC(thermal properties )

Z-potential(surface charge of dispersed particles in liquids)

AFM(Spread on a substrate, thickness and roughness of surface)

UV-VIS and PL spectroscopy(optical properties)

BET,BHJ(surface area, pore volume)

Raman spectroscopy(disorder in crystal structure )

FTIR spectroscopy(detection of functional groups )

XPS (determine the location and ascription groups)
