Photoluminescence Spectra of Carbon Clusters Embedded in SiO_2
スポンサーリンク
概要
- 論文の詳細を見る
Composite films of carbon and SiO_2 were prepared by a rf cosputtering technique and their photoluminescence and absorption spectra were measured. A strong and broad photoluminescence peak located around 2.2 eV (visible to the naked eye) was observed for the samples with relatively low carbon concentrations. The blue shift of the photoluminescence peak observed with decreasing carbon concentration and the increased absorption in the UV region strongly suggest that carbon clusters comparable to or smaller than C_<60> formed in the SiO_2 matrices are responsible for the strong photoluminescence.
