[摘要]：Crystallization behavior of the oxide semiconductor ZnO in zinc borate glass was investigated. The precipitated crystalline phase of glass ceramics containing a small amount of Al(2)O(3) was alpha-Zn(3)B(2)O(6) whereas that of the glass ceramics containing a large amount of Al(2)O(3) was ZnO. It was found that the c-oriented precipitation of ZnO in a glass ceramic was brought about by the in-plane crystal growth of needle-like ZnO crystallites along the a-axis. Amount of Al(2)O(3) that can make glass network affected the coordination state of B(2)O(3) in the glass, and a three-coordinated BO(3) unit was preferentially formed in the glass containing a higher amount of Al(2)O(3). The present results suggest that crystallization of ZnO from multi-component glass is dominated by the local coordination state of the mother glass. (C) 2011 Elsevier B.V. All rights reserved.
