摘要：

A detailed study of the optical absorption bands induced by titanium in phosphate glasses has been carried out. Optical absorption, diffuse reflectance and EPR techniques have been used to characterize the centers responsible for these bands, which occur in the near ultraviolet and visible region of the spectrum. Three kinds of centers have been identified: Ti3+ ions in a distorted octahedral environment, which show the 10 Dq value characteristic of these type of centers (17700 cm-1); Ti4+ ions in octahedral coordination presenting a charge transfer transition in the near UV region; and Ti3+ - Ti4+ mixed complexes, which originate an optical absorption band at 450 nm.
