Near-infrared dyes

Abstract: This chapter provides a general overview of and information on near-infrared (NIR) absorbing dyes. NIR absorbing dyes have been considered in various recent high-tech applications such as laser optical recordings, laser printings, laser thermal writing displays, infrared photography and biological/medical applications. In optoelectronic application areas, especially, NIR absorbing dyes are being developed and new structural designs of the dye chromophore molecules are being studied. In this context, the chapter discusses general overviews and introductions for NIR absorbing dyes.
