Abstract

We have observed four bulk luminescence peaks from Spectrosil glasses stimulated by low energy electron bombardment in ultra-high vacuum. The lifetimes of these bands were measured by chopping the incident electron beam and measuring the fluorescence decay. It was found that one of them has a markedly long lifetime (2.1 ms) compared with the others (<10μs). After annealing at 500° C for one hour and pumping down overnight, characteristic spectral lines from OH*, H*, K*, a molecular band, and an unidentified line appeared at room temperature during electron irradiation. A possible mechanism for this long-lifetime luminescence will be discussed.
