Photoanodes composed of n-GaAs in contact with electrolytes exhibit distinctive hotoelcotrcohemical effect on illumination. They are expected to give high sunlight conversion fficiencies. However, n-GaAs tends to undergo photoanodic docomposition when working in olutions of ordinary electrolytes. Attempts have been made to search for a more suitable lectrolyte. By thermodynamic as well as kinetic considerations and by comparing the hotoanodic ehaviors of n-GaAs in different electrolytes, wo found that the triethanolamine (TEA) complex f the Fe~(3+)/Fe~(2+) couple in NaOH solution fullfills the requirements to some extent. This omplex system has an equilibrium potential of about -1.05 V (vs. SCE), which is more negative han the anodic docomposition potential of n-GaAs in alkaline medium( -0.97 V). Besides, its nodic polarization is not too severe. These suggest that the Fe-TEA complex is a better redox ystem for n-GaAs photoanode, at least under conditions of not too heavy load. The comformity etween the experimental results and theoretical predictions indicates that the method of nalysis is perhaps valid and may serve as a guidance in selecting redox eletrolytes for emiconductor-electrolyte photoelectrode systems.

由n-GaAs与电解液接触组成的光阳极在光照下表现出明显的光电化学效应,并预期能给出较高的日光能转化效率.但问题在于:当在通常的一些氧化-还原电解液中工作时,n-GaAs倾向于发生光阳极性腐蚀分解.为了抑制这种腐蚀倾向,本工作在寻找合用的替代电解液方面进行了探索.基于热力学和动力学两方面的考虑,并根据n-GaAs在几种电解液中光阳极行为的比较,初步找出Fe~(3+)/Fe~(2+)氧化-还原对与三乙醇胺在NaOH中的配体络合物在一定程度上满足所提要求.这种络合物电解液的平衡电势约为-1.05V(对饱和甘汞电极).比n-GaAs在碱液中阳极分解的平衡电势-0.97V为负,并且电氧化时的极化倾向也不太大.这些都提示:至少在负荷不太高的情况下,它可以用作较好的替代电解液.实验结果与理论预期的情况颇为相符,这表明所作的分析推理是适用的,为进一步探讨各种光电极相应电解液的选择指出了途径.

The preparation of nanoscale rare earth—micronscale inorganic mineral particle composite material by sol-precipitation method has been studied in this paper. The product can be used as sunlight conversion agent in agricultural film.The composite process not only can reduce the aggregation of nanoscale rare earth material and the price of the products, but also make the products have multifunctional properties. The factors,which have effects on the properties of samples in the preparing process,are also discussed.The results show that the addition of Y~(3+) ion can enhance the luminescent intensity of the system; the finer the core particle, the higher the luminescent intensity of the sample; the reaction temperature has little influence on the intensity of the product, and this can be very useful in practical application.

报道了用溶胶-沉淀法制备可用于农用转光薄膜的纳米级稀土-微米级无机填料复合转光材料,一方面解决了纳米级稀土的团聚问题,降低了最终产品的价格,另一方面使制备出的样品具有多功能性,并讨论了制备过程中各种因素对转光性能的影响。在实验过程中发现Y3+的加入对稀土铕无机发光体系有很大的增强作用;作为载体的中心粒子粒度越细,所得样品的发光强度能大幅度增加;反应温度对样品发光强度影响不大,可在室温范围进行转光材料的复合制备,这有利于进一步的推广应用。
