Abstract :
We present white light generating nonradiative Forster resonance energy transfer at a rate of (2 ns)-1 directly from epitaxial InGaN/GaN quantum wells to CdSe/ZnS heteronanocrystals in their close proximity at chromaticity-coordinates (x,y) = (0.42,0.39) and correlated-color-temperature CCT = 3135 K.
