Outline of Final Research Achievements

Light control and manipulation in near-infrared region has widely attract much attentions because of their potential application in optical fiber, biosensing and photo voltaic system. In order to light trapping in near-infrared region, array of gold nanofins with ultra high aspects has been prepared in solid substrates based on nanocoating lithography. This Au nanoarray can successfully trap near infrared light. In addition, dye molecules which were introduced into the gaps of Au nanofins showed emphanced fluorescence emission compared with the dye simply embedded polymer layer without Au nanofins. And we also found the nanoconfined effect on molecular assembly of liquid crystal molecules and these molecules self-assembled columnar structures with specific orientation in the gaps of Au nanofins.
