零维(0D)金属卤化物是一类新兴的发光材料体系,它们具有独特的“主-客”体结构,即独立的阴离子金属卤化物多面体客体规则有序地分布在有机阳离子或碱金属阳离子形成的主体框架中。这种具有相对较“软”晶格的0D金属卤化物材料的发光主要源于自陷激子(Self-trapped excitons,STEs)复合,其通常呈现出宽带发射,且具有大的斯托克斯位移。通过筛选不同的及多样化构型的金属卤化物多面体,将其与合适的有机阳离子或者Cs+等组合,可形成多种新型结构的0D金属卤化物,并实现丰富的STEs发光特性,其可调节的荧光发射不仅可以覆盖整个可见光区,还可实现单相白光或近红外发光,成为光致发光材料研究领域的一个热点和重点。基于此,本文结合本课题组在该领域的研究工作基础,首先讨论了0D金属卤化物的光致发光机理;其次,介绍了具有不同多面体构型的0D金属卤化物材料的发光特性及应用;最后,总结了0D金属卤化物目前亟待解决的关键科学问题,并对0D金属卤化物的未来发展方向进行了展望。

增强纤维材料PA66可以有效地改善塑料制件的力学性能,但是充填过程的剪切流动又对PA66的纤维起到了拉伸作用,从而引起纤维取向。这种取向的产生一方面会导致制件不同方向的收缩,另一方面在熔接线区的纤维取向方向因平行于熔接方向而大大降低其熔接线强度,制件整体强度下降。探讨了用计算机模拟增强纤维PA66材料充填过程引起的纤维取向的计算方法,借助计算机对有强度要求的增强纤维PA66材料制件的熔接线强度的形成和影响其强度的因素逐一进行剖析,提出了改变浇口类型以改变纤维取向方向来提高制件整体强度的方法。

The resource development and changes of hydrological regime, sediment and water quality in the Mekong River basin have attracted great attentions. This research aimed to enhance the study on transboundary pollution of heavy metals in this international river. In this study, eight sampling sites were selected to collect the bed sand samples along the mainstream of the Mekong River. In addition, the contents of 5 heavy metal elements and their spatial variability along the mainstream of the river were analyzed. The geoaccumulation index （l^eo） and potential ecological risk analysis were employed to assess heavy metal pol- lution status in the mainstream of the Mekong River. The results show that the average con- tent of the heavy metal elements Zn is 91.43 mg/kg, Pb is 41.85 mg/kg, and As is 21.84 mg/kg in the bed sands of the Upper Mekong River, which are higher than those （Zn 68.17 mg/kg, Pb 28.22 mg/kg, As 14.97 mg/kg） in the Lower Mekong. The average content of Cr in the Lower Mekong is 418.86 mg/kg, higher than that in the Upper Mekong （42.19 mg/kg）. Luang Prabang has a very high Cr concentration with 762.93 mg/kg and Pakse with 422.90 mg/kg. The concentration of Cu in all of the 8 sampling sites is similar, except for in Jiajiu with 11.70 mg/kg and Jiebei with 7.00 mg/kg. The results of the geoaccumulation index reveal that contaminations caused by Zn and Pb while Pb and As are more than those by Zn in Upper Mekong. Cr is the primary pollutant in the Lower Mekong, especially at Luang Prabang and Pakse. Slight pollution with As also occurs in Pakse. The potential ecological risk index indi- cates that the potential ecological risk of heavy metals in the mainstream of the Mekong River is low. We argue that the pollution of water quality and contamination of heavy metals in bed sediment caused by mining of mineral resources or geochemical background values in the Mekong is not transmitted from the Upper to the Lower Mekong because of the reservoir sedimentation and
