Abstract | Light-emitting diodes with vertical stacking geometry were fabricated and characterized. Color-tunable emission and white-light emission has been demonstrated in Stacked-LED (SLED). Emissions of different colors, ranging from green-blue, to pink-purple, to yellow-orange and white light emission have be achieved by adjusting the relative intensity of two or three individual emission bands, which in turn are controlled by adjusting voltage supply. Compared to conventional lateral side-by-side geometry, the shift of white color chromaticity with respect to viewing angles is less in the case of SLED device. The farthest shift of white CIE coordinate point away from the pure white CIE coordinate is (0.29, 0.29) in SLED compared to (0.37, 0.35) in the commerical available lateral packaged structure. This vertically-stacked LED is poised to open new frontiers in high performance color-tunable LEDs. © 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. |
