简介:用电化学阳极氧化法制备了一定孔隙率的多孔硅样品,然后用脉冲激光沉积法以PS为衬底生长一层ZnS薄膜.用X射线衍射仪、扫描电子显微镜和荧光分光光度计分别表征了ZnS薄膜的结构、形貌和ZnS/PS复合膜的光致发光性质.XRD结果表明,制备的ZnS薄膜沿G—ZnS(111)方向择优生长,结晶质量良好,但衍射峰的半峰全宽较大;SEM图像显示,ZnS薄膜表面出现一些凹坑,这是衬底PS的表面粗糙所致.室温下的光致发光谱表明,沉积ZnS薄膜后,PS的发光峰蓝移.把ZnS的蓝绿光与PS的橙红光叠加,在可见光区450~700nm形成了一个较宽的光致发光谱带,ZnS/PS复合膜呈现较强的白光发射.

简介:水体沉积物是水生生态系统重要的组成部分,沉积物污染将影响整个水生生态系统,因此有必要构建科学全面的水体沉积物质量评价方法,为环境污染修复与监管提供科学依据。已有文献报道了多种沉积物质量评价方法。其中,证据权重法通过对不同的证据进行测定与整合,弥补了传统评价方法的不足,可以对沉积物质量进行科学全面的评价。本文对证据权重法中化学分析、生物毒性和底栖生物群落结构3种证据的测量方法、赋权方法、证据整合与信息解译方法进行了系统评述,并以淡水河为例介绍了用多目标决策理想点法(TOPSIS)整合数据进行沉积物质量综合评价的方法。
