Abstract
Official abstract text for this publication.
The present invention provides a porous glass having excellent antireflection performance for visible light. A porous glass includes a porous layer which is mainly composed of silica and which has pores attributed to spinodal phase separation and pores attributed to binodal phase separation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A porous glass comprising: a porous layer including silica, and a matrix layer, wherein the porous layer is provided on the matrix layer, wherein pores attributed to spinodal phase separation and pores attributed to binodal phase separation are formed in the porous layer, and in the porous layer, the proportion of pores attributed to spinodal phase separation with respect to the proportion of pores attributed to binodal phase separation is redu…
