摘要: This letter reports on the improved performance of a pseudomorphic ultraviolet light-emitting diode (LED). At 100 mA input current, 9.2 mW quasi-CW output power was measured in calibrated integrating sphere. The addition heat sink, required for CW and higher operation, introduced numerical aperture 0.86, 72 pulsed mode at 1.7 A, indicating that total exceeds when corrected by coupling factor. high characteristic temperature 983 K instrumental achieving these record powers an LED with wavelength shorter than 265 nm.
