چکیده انگلیسی
The creation and characterization of Ce doped surface regions in 6Li enriched silicate glasses for cold neutron detection is described. A diffusion layer of a dried solution containing cerium III acetylacetonate hydrate was thermally diffused into monolithic glass samples under a reducing atmosphere. The diffusion characteristics of the mixed valence cerium compound were assayed with Rutherford Backscattering Spectrometry. The Ce diffusion activation energy within the glass was found to be 411â¯Â±â¯53â¯kJ/mol (4.26â¯Â±â¯0.55â¯eV). Radiation induced color centers formed on the diffusion samples as an effect of using alpha bombardment measurements. The ratio of Ce valence states of the diffused cerium was assayed as a function of depth with X-ray Photoelectron Spectroscopy, and the signal from Ce for the color centers was compared to the unirradiated sample surface.
