Influence of Annealing on Microstructure and Photoluminescence Properties of Al-Doped ZnO Films

Effect of annealing temperature and time on the microstructure and photoluminescence (PL) properties of Al doped ZnO thin films deposited on Si (100) substrates by sol-gel method was investigated. An X-ray diffraction (XRD) was used to analyze the structural properties of the thin films. All the thin films have a preferential c-axis orientation, which are enhances in the annealing process. It is found from the PL measurement that near band edge (NBE) emission and deep-level (DL) emissions are observed in as-grown ZnO∶Al thin films. However, the intensity of DLE is much smaller than that of NBE. Enhancement of NBE is clearly observed after thermal annealing in air and the intensity of NBE increases with annealing temperature. Results also show that the PL spectrum is dependent not only on the processing temperature but also on the processing time. The DLE related defects can not be removed by annealing, and on the contrary, the annealing conditions actually favor their formation.     

Microstructure and Properties of Mg-10%Al-(0～3%)Di Alloys

The effects of didymium(Nd:Pr=3:1)on the microstructure and mechanical properties of Mg-10%Al alloy were studied with the additions of 0～3%Di. The small block-like Al2(Nd,Pr) phase appears in 1%Di alloy, the block-like Al2(Nd,Pr) and needle-like Al11(Nd,Pr)3 phases appear synchronously in 2%Di and 3%Di alloys, while the network of (Mg17Al12) β phase is broken up. The tensile properties can be improved with the addition of didymium. When the addition of didymium in Mg-10%Al alloy reaches 2%, the alloy exhibits the best combination of strength and ductility, but the strength and ductility drop at the addition of 3%Di due to the obvious increase of the size and quantity of the needle-like Al11(Nd,Pr)3 phase.

CeO2基固体电解质材料的掺杂强化

强度低是CeO2基电解质材料的一个主要缺点，实验发现，加入Al2O3可以显增加CeO2基材料的强度，原因是掺杂的Al2O3在CeO2中产生压缩应力；阻碍裂纹的进一步扩展，另外，Al2O3分布在晶界处，将会导致裂纹偏转，最大弯曲强度对应的Al2O3添加剂量摩尔分数为3%，加入Al2O3还可以促进材料烧结，使烧结温度降低到1500℃以下，但会使CeO2基电解质的电导率下降。
