4.2.3 Quantum Efficiency and LED Power
{"Image DocumentName": "4.2.3 Quantum Efficiency and LED Power", "Image ImageDescription": "Example 4-5: A double-heterojunction InGaAsP LED emitting at a peak wavelength of 1310-nm has radiative and nonradiative recombination times of 30 and 100-ns, respectively. The drive current is 40-mA. From Eq. (4-11), the bulk recombination lifetime is. t = tr.tnr/(tr + tnr) = 30 x 100 / ( ) ns. = 23.1 ns.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
