Abstract

ZnO surface crystallized glass-ceramics were fabricated using K ₂O-CaO-ZnO-B₂O₃-SiO₂-Al ₂O₃ glass system. Precipitation of Zn-containing oxide crystallites was affected by the chemical composition of borate glass, especially the amount of Al₂O₃. Substitution of SiO ₂ for B₂O₃ brought selective crystallization of ZnO without precipitation of α-Zn₃B₂O₆. ZnO-precipitated glass-ceramics showed surface crystallization with submicron-sized crystallites, which assured transparency of these glass-ceramics. The obtained glass-ceramic shows free exciton emission, which is similar to emission of ZnO single crystal.
