• It is found that in fused quartz made in reducing condition three absorption bands having peaks at 2.3, 4.1 and 5.6 ev and in fused quartz made in oxidizing condition two absorption bands having peaks at 4.1 and 5.6 ev are produced by exposure to X-rays. The stability of these centers is studied by bleaching with temperature and light. The band having peak at 5.6 ev is found to be composed of two bands having peaks at 5.6 and 5.87 ev. The band at 2.3 ev is studied to be due to electrons trapped by negative-ion vacancy or by an aggregate of negative-ion vacancies. The luminescent center of fused quartz is proposed to be interstitial silicon atom. It is concluded that fused quartz has in fairly extent short range order of crystal.
