Phosphate-based glass materials have potential use as biomaterials, because of their chemical composition similarity to the natural bone. In this paper we present an IR, Raman and ESR study on glass systems such as P2O5-CaO-Li2O, where the proportion of P2O5 remains constant at 50 mol % and those of Li2O and CaO modify from 10 to 40 mol %. The IR and Raman spectra allow us to identify the structural units which appear in the structural network of these phosphate glasses and also the network modifier role of Ca2+ and Li+ ions. The ESR spectra of the gamma irradiated samples with a 60Co source, are characterized by the hyperfine doublet of 31P isotope (I= 1/2). By representing the ESR signal intensity versus the absorbed doses in the range 100-1500 Gy, a linear dependence was obtained, which proves that the glass system P2O5-CaO-Li2O could be successfully used in the clinical dosimetry and industry.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
