• A new rhodamine derivative with red light absorption was designed and synthesized. The absorption properties and thermal stability of the rhodamine derivative were discussed. We also studied the characteristics of a super-resolution recordable disk with a modified rhodamine recording layer and a poly(methyl methacrylate) (PMMA) contrast enhanced layer. A sample disk, which consists of a spin-coated rhodamine derivative recording layer and a PMMA contrast enhanced layer, showed excellent recording and readout characteristics with a carrier-to-noise ratio (CNR) of about 43 dB for a mark length of 200 nm (laser wavelength = 635 nm, numerical aperture = 0.60). These results indicate that the rhodamine derivative dye is a promising candidate for optical recording by a super-resolution near-field structure (super-RENS) technique.
