Conduction electron spin resonance of Pt-nanoparticles in porous Al2O3 membranes

An electron spin resonance (ESR) investigation of Pt-nanoparticles electrodeposited in the channels of porous Al2O3 membranes has been performed in the temperature range 6-50 K. Pt-particle mean size was evaluated by means of Kawabata theory that relates ESR line width to metal particle size. A comp...

Description
Summary:An electron spin resonance (ESR) investigation of Pt-nanoparticles electrodeposited in the channels of porous Al2O3 membranes has been performed in the temperature range 6-50 K. Pt-particle mean size was evaluated by means of Kawabata theory that relates ESR line width to metal particle size. A comparison with the effective crystallite mean size obtained from the X-ray diffraction analysis is given.
