Description
Summary:Effect of 80KeV proton radiation with fluences of 10(1(4-2x10(1(6 protons/cm(2) on the optical properties and microstructure of type-GG17 borosilicate glass as a candidate material for rubidium spectra lamp envelope was investigated. The change in microstructure before and after proton radiation was evaluated by means of UV-vis-NIR spectroscopy, X-ray photoelectron spectroscopy (XPS) and positron annihilation lifetime spectrometer (PALS). The experimental results show that under radiation of 80KeV some broken Si-O bonds were induced and thus the number of non-bridge oxygen (NBO) increased. These irradiation-induced defects caused the degeneration of optical property and loosened glass structure which accelerates rubidium diffusion into lamp envelop.
