Introduction, can satisfy the present and future needs of the society producing the minimum impact on the environment. For such a purpose, a huge international research effort is being devoted to the study of new systems of energy production, in particular in the field of nuclear energy. On the one hand, new fis

Studied Materials: a-SiO, and MgO their structure is very different: a-SiO. is amorphous and has a pronounced covalent character, while MgO is crystalline and has a very ionic character. This chapter deals with the structure of both materials and with the characteristics of the samples used in this thesis.

General Features of the Ion Beam Induced Luminescence in Amorphous Silicaent in the silica IL spectra: a red band peaked at 1.9 eV (650 nm) and a blue band at 2.7 eV (460 nm). Two important questions when studying IBIL in silica will be also answered in this chapter. The first question is the origin of the blue band, as there is a controversy in the literature when deali

Exciton Mechanisms and Modeling of the Ionoluminescence in Silica at 650 (1.9) and 460 nm (2.7 eV) in silica as a function of the irradiation fluence at room temperature. Some of the data shown in Chap. . will be used in this chapter to introduce the physical model here presented. In particular, the results obtained for dry silica (IR, low OH content) will be evo

Conclusions and Prospects for the Futureon of the capability and the power of the ionoluminescence technique (IL, which is not a widely known IBA technique) to study . the level and evolution of the microscopic and macroscopic damage in materials. During this thesis the development of the IL technique has been implemented in new beamlines
