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370～384 nm, 可见发射峰位于468 nm附近； 粉体的平均粒径在100 nm左右。

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 luminescence 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 ultra-violet 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.
