Austrian chemists have developed a red phosphor that could improve the efficacy of white LEDs, by creating a narrow peak of emission at 614nm – in the middle of the eye’s 610-620nm peak red sensitivity. The material is a particular form of Sr[Li2Al2O2N2]:Eu2+, dubbed ‘salon’ by the researchers, which “meets all the requirements for the ...
