纳米CuCl晶簇室温光吸收谱

Room Temperature Optical Absorption Spectra of Nanometer CuCl Clusters

实验测定了平均尺寸４．２ｎｍＣｕＣｌ晶簇的室温近紫外和可见光吸收谱线，给出了Ｈｅ－Ｎｅ激光束辐照下的光吸收谱线，在３．１８７ｅＶ处有一个宽度０．

The optical absorption spetra of average size 4.2 nm CuCl clusters in near ultra violet and visible regions are determined at room temperature. The optical absorption spectra in two samples irradiated by He Ne laser beam are also shown. A sharp peak with the width of 0.62 meV in an absorption spectrum of CuCl nanoclusters irradiated by laser beam is observed at 3.187 eV.
