Radiation-induced luminescence and photoluminescence from sol–gel silica glasses and phosphosilicate glasses by 1MeV H+ irradiations

Radiation-induced luminescence (RIL), photoluminescence (PL) and PL excitation (PLE) spectra have been applied to the study of photon emission from sol-gel silica glasses and phosphosilicate glasses. The photoemissions from oxygen excess-related defects are observed at about 1.98eV by PL and RIL. Th...

Description
Summary:Radiation-induced luminescence (RIL), photoluminescence (PL) and PL excitation (PLE) spectra have been applied to the study of photon emission from sol-gel silica glasses and phosphosilicate glasses. The photoemissions from oxygen excess-related defects are observed at about 1.98eV by PL and RIL. The irradiation of 1MeV H+ is investigated with the excitation bands at 2.11 and 2.13eV by PLE. The effects of ion irradiation on the glass samples show that the defects were increased in the silica glass and decreased in the phosphosilicate glass.
