中文摘要：

MgxZn1-xO材料是一种新型的光电功能材料,近年来受到人们的广泛关注。文章采用Sol-Gel法制备了MgxZn1-xO粉体,研究Mg含量对MgxZn1-xO结构和发光性能的影响,结果表明在x从0到1的整个区间中MgxZn1-xO样品存在六方纤锌矿与面心立方两种结构,当x〈0.2时为六方纤锌矿结构,x〉0.8时为面心立方结构,在两者之间为其混合结构;光谱分析表明不同组分的MgxZn1-xO样品均具有紫外和可见发射特性,紫外发射峰位于370～384nm,可见发射峰位于468nm附近;粉体的平均粒径在100nm左右。

英文摘要：

MgxZn1-xO has been subjects of intense attention as a novel photo-electronic functional material in recent years. In the present paper, MgxZn1-xO powders were prepared by sol-gel method. Effects of Mg contents on MgxZn1-xO structure and lumi- nescence properties were studied. The authors observed that MgxZn1-xO exhibited two kinds of structures, hexagonal wurtzite and face center cubic while x was in the range of 0 and 1. The MgxZn1-xO powders were hexagonal wurtzite structure with ,x〈0. 2, face center cubic structure with x〉0. 2 and their blend structure with x between 0.2 and 0.8. Luminescence spectrum analysis indicated that all MgxZn1-xO samples with various composition showed luminescence of ultraviolet and visible light. The ultraviolet emission peak was from 370 nm to 384 nm and the visible emission peak was around at 468 nm. The average size of MgxZn1-xO powders was about 100 nm.
