AbstractThe high-density, two-dimensional arrays of micrometer-sized InGaN/GaN light-emitting diode (LED) were used to measure the fluorescence excitation and lifetime. The micro-LEDs used were 64×64 arrays of 20-μm-diameter micro-disk elements and were fabricated on sapphire-substrate, MOCVD-grown InGaN/GaN wafers. A microscope image of ultraviolet (UV) micro-LED downconversion in fluorescein was shown. It was shown that the micro-LED are suitable source for time-resulved fluorescence spectroscopy. Several types of fluorescent dye were array-excited by a UV device and examined optically to test the fluorescence-excitation capability.
