研究了粘土表面的光化学能量传递。通过改变环境气氛，可以调节染料分子的吸附取向角。结果表明，染料间的能量转移效率可以通过染料间相对取向的变化来控制。取向因子和光谱重叠因子的变化是影响能量传递效率的主要因素。该技术将有助于构建诸如变色材料和捕光系统等光功能材料。(C)2014爱思唯尔有限公司版权所有。
Photochemical energy transfer was examined on the flat clay surface. By the change of surrounding atmosphere, the molecular adsorption orientation angle of dyes can be modulated. It is turned out that the energy transfer efficiency between dyes can be controlled by the relative orientation change between dyes. The change of orientation factor and spectral overlap factor was the main factor to affect the energy transfer efficiency. This technique would be useful to construct the photo-functional materials such as chromic and light harvesting system. (C) 2014 Elsevier Ltd. All rights reserved.
