退火对ZnO:Al薄膜光致发光性能的影响
溶胶-凝胶法 ZnO:Al薄膜 退火处理
2009/2/7
采用溶胶-凝胶工艺在石英衬底上制备ZnO:Al(AZO)薄膜,通过不同温度的退火处理,研究了退火对AZO薄膜结构和光致发光特性的影响。XRD图谱表明:所制备的薄膜具有c轴高度择优取向,随着退火温度的升高,(002)峰的强度逐渐增强,同时(002)峰的半高宽逐渐减小,表明晶粒在不断增大。未退火样品的光致发光(PL)谱由361 nm附近的紫外带边发射峰和500 nm附近的深能级发射峰组成。样品经退火后...
A study has been made on the behavior of Al/p-CdTe thin film junction grown by thermal evaporation method. I-V characteristics show that the Al makes Schottky contact with p-CdTe. The variation of jun...

We have generated cubic Al alloys as commensurate single crystals on the tenfold-symmetry surface of the quasicrystalline Al-Ni-Co alloy by ion bombarding its surface. We find that the crystal-quasicr...
机械合金化Al-Mg-Si-Cu元素粉末的特性
机械合金化 Al,Mg,Si和Cu元素粉末 物性 合金化特性
2010/3/9
Al,Mg,Si和Cu元素粉末按6061铝合金成分配比进行了机械合金化(MA),对其物相、合金化特性、晶格常数、晶粒尺寸及点阵应变作了测定和分析讨论。MA初期晶粒尺寸可以达到纳米级,最小晶粒尺寸20nm;粉末点阵应变最终达0.2%;Al晶格常数变化的总趋势是不断减小;塑性较好的元素粉末可在“面上”作短程扩散,合金化易于进行,可实现完全合金化;硬度较高的脆性元素粉末只在“点上”作短程扩散,合金化不易...
