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

| Abstract: | 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 struc... |
