In this dissertation, we optimized the thinkness of each layer of TFEL devices using the layered optimization method to obtain ZnS: Ce〓 TFEL devices. Accoding to the energy level structure of Ce〓, two criteria for distinguishing the EL of Ce〓 were found out, from which it was conduded that the TFEL of ZnS: Ce〓 comes from 5d→4f transition of Ce〓. The measurement of brightness waveform showed that the TFEL of ZnS: Ce〓 was the luminescence from independent centers. and there were the field induced-delocalization in this process anf it〓s the cause of low TFEL efficiency of ZnS: Ce〓. In this dissertation, different influence factors on TFEL of ZnS: Ce〓 were sdudied. The influence of different host lattice is different: The blue/green ratio of ZnS: Ce〓 in hexagonal system of ZnS is larger than that in cubic system of ZnS, and the TFEL peaks in hexagonal system of ZnS moves toward longer wavelength compared with that in cubic system of ZnS. The adding buffer layer was used in this stage. The solubility of Ce〓 in ZnS was small and it was another limit to TFEL brightness of ZnS: Ce〓 device. The solubility of Ce〓 increased ten times when using Li ions as flux, so that the TFEL brightness of ZnS: Ce〓 was enhanced. It was found that the appearing of ZnO in active layer improves the TFEL of ZnS: Ce〓: the brightness and the wave range of ZnS: Ce〓TFEL were enhanced.
本文采用TFEL的分层优化方案,优化组合了各膜层厚度,选择最佳制备条件,得到了ZnS:Ce〓的TFEL;根据Ce〓的能级结构,找到了判别Ce〓的EL的两个简单依据,并据此断定ZnS:Ce〓的TFEL的两个发射峰分别属于Ce〓的〓和〓跃迁;亮度波形测量表明ZnS:Ce〓的TFEL属于分立中心发光,分析认为在此过程中存在着较严重的场致离化,这也是ZnS:Ce〓的TFEL效率较低的一个原因;本文考查了影响ZnS:Ce〓的TFEL的各种因素,发现:基质的晶体结构对ZnS:Ce〓的TFEL有所影响,在六角相ZnS中Ce〓的TFEL优于立方相ZnS中Ce〓的TFEL:发射峰的蓝-绿比相对较大,且光谱向短波方向移动,在此项研究中本文采用了在发光层前增镀过渡层的办法,过渡层为六角晶相的ZnO;限制ZnS:Ce〓的TFEL器件亮度的一个原因是Ce〓在ZnS中的溶解度低,本文用Li离子作助溶剂增大了Ce〓的溶解度,增大幅度为一个量级,并且ZnS:Ce〓的TFEL亮度明显提高;从ZnS:Ce〓的TFEL光谱来看ZnS:Ce〓的TFEL波长覆盖范围较小,亮度也不高,达不到做为白色TFEL材料的要求,需要寻找新的白色TFEL材料;在研究ZnS:Ce〓的TFEL中还发现:发光层中ZnO的出现有利于ZnS:Ce〓的TFEL:发射峰变宽、亮度增大。

Using of optical microscopy, X-ray diffraction, transmission electron microscopy, hardness and tensile testing, the effect of thermal exposure at high temperatures on the microstructures and of high-temperature tensile properties of rapidly solidified AlCrYZr have been studied. The results show that there are two main phases,Al20Cr2Y(cubic, a=1.437 nm) and DO23Al3Zr(terganal, a=0.4 013 nm , c= 1.732 nm), in the as-solidified alloy. The Al20Cr2Y phase can maintain its cubic structure at 500℃, but the particles coarsen remarkably and even become lumpish. In coarse lumpish Al20Cr2Y phase the plane faults and twin structures exist.
