Origin of efficiency droop in GaN-based light-emitting diodes
Min-Ho Kim,Martin F. Schubert,Qi Dai,Jong Kyu Kim,E. Fred Schubert,Joachim Piprek,Yongjo Park +6 more
TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.

Effect of Selected Luminescent Layers on CCT, CRI, and Response Times.
TL;DR: An experiment with luminescent layers consisting of a mixture of selected phosphors and polydimethylsiloxane (PDMS) yielded a source of white light with a CRI value of greater than 85, and was examined in order to examine their potential use in visible light communications (VLC).
