Mössbauer effect of 151 Eu in europium salen complex nanoparticles

The use of Mössbauer spectroscopy to investigate nanoparticle systems is fairly widespread. In this study, nanoparticles of a europium salen complex, NH 4 Eu (salen) 2 , were prepared by the sol–gel method, and its properties investigated using infrared and Mössbauer spectroscopy. The size of the nanoparticles was measured using an atomic force microscope. The Debye temperature of the nanoparticles was determined from the Mössbauer spectrum and compared with the Debye temperature of the salen complex previously reported. The infrared spectral data support the Mössbauer spectroscopic results.
