Abstract

A new integrated fluorescence-detection hybrid device with a photodiode and an organic light-emitting diode (OLED), and its characteristics are presented. To detect the fluorescent signal using OLED as a light source, a finger-type photodiode with low parasitic resistance was designed, which utilizes the side depletion region in the p⁺n junction. In addition, OLED was designed to have the peak intensity at an excitation wavelength from rhodamine 6G. The integrated fluorescence-detection hybrid device fabricated had a background signal of 153 nA and a limit of detection of 1 μM, and was applied in the competitive assay.
