Blue light emitting diode exceeding 100 % quantum efficiency
1 Introduction GaN-based light-emitting diodes (LEDs) deliver the desired high efficiency only at relatively low injection current density [1]. At the elevated current densities required in practical high-brightness applications , the efficiency is substantially reduced. This efficiency droop phenomenon has been intensely investigated for a number of years, but the physical mechanisms behind it...

متن کاملEnhancement in external quantum efficiency of blue light-emitting diode by photonic crystal surface grating
Blue photonic crystal light-emitting diodes were evaluated with photonic crystal hole patterns. The diameter of the holes, lattice constant, and emission wavelength were selected to be 110, 220 and 450 nm, respectively, to attain a maximum enhancement in the wallplug efficiency. The improvement in external quantum efficiency was 30–50%. Changes in voltage characteristics caused by the etched ho...

متن کاملCuring efficiency of high-intensity light-emitting diode (LED) devices.
We evaluated the curing efficiency of 4 high-intensity light-emitting diode (LED) devices by assessing percentage of residual C=C (%RDB), surface microhardness (SM), depth of cure (DC), percentage of linear shrinkage-strain (%LS), and percentage of wall-to-wall contraction (%WWC). The light-curing units tested were a QTH light, the Elipar TriLight (3M/ESPE), and 4 LED devices - the Allegro (Den...
