摘要：

An electron microscopic study of a series of photoconducting oxide glasses in the systems CdO/B(2)O(3)/SiO(2), CdO/B(2)O(3)/GeO(2) and PbO/Al(2)O(3)/SiO(2), has shown the essential diphasic nature of these materials. The samples were examined by replica techniques, in transmission and by scanning electron microscopy. Two-liquid features have been identified, as has very fine-scale crystallisation, both on the basis of textures of fracture surfaces and of electron diffraction patterns. Physical models proposed to explain the electronic properties of glasses such as these must take account of this obvious two-phase nature of such materials.
