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.

Emerging cool white light emission from Dy3+ doped single phase alkaline earth niobate phosphors for indoor lighting applications
Amit K. Vishwakarma,Kaushal Jha,M. Jayasimhadri,B. Sivaiah,B. Sivaiah,Bhasker Gahtori,Bhasker Gahtori,D. Haranath +7 more
TL;DR: The study reveals that BaNb2O6:Dy(3+) phosphor could be a potential candidate for near ultra-violet (NUV) excited white-LED applications and chromaticity coordinates and correlated color temperature (CCT) endorse cool white-light emission from the phosphor.
