In order to clarify the manometer size effect of the photo-polymerization reaction in C_<60> aggregates, we have investigated PL of the materials photo-polymerized from two different types of C_<60> aggregates whose average size was considered to be different from each other. One type of C_<60> aggregates was formed from C_<60> in toluene, benzene, and CS_2 and its size were estimated to be in several manometer region. The other type of them was formed from C_<60> in solvent mixtures composed of two component in which has very different solubility and the size was reported in several hundred manometers. It has been found that the observed spectral difference between them can be attributed to the different dimensional covalent bonding networks

为了阐明C&lt；60&gt；聚集体中光聚合反应的压强尺寸效应，我们研究了两种平均尺寸不同的C&lt；60&gt；聚集体的光聚合材料的发光。C&lt；60&gt；在甲苯、苯和CS2中形成了一种C&lt；60&gt；聚集体，其尺寸估计在几个压力计范围内。另一类是由C&lt；60和Gt；在由两个组分组成的溶剂混合物中形成的，它们的溶解度非常不同，据报道其大小可达数百个压力计。发现它们之间的光谱差异可以归因于不同维度的共价键网络
