Abstract
The optical properties in the uv-visible region of epoxy glass composi te containing 0, 15, 35 and 55% by weight glass microballoons are repo rted. The obtained optical data are analysed in terms of absorption fo rmula for non-crystalline materials. Assuming that non-direct transiti ons in the k-space are involved values of optical band gap (E(opt)) we re determined. From the Urbach edges, the width of the tail of localiz ed states in the band gap (E) were evaluated at room temperature.
