Ultrathin Layer

we designed and fabricated a white organic light-emitting device based on{[2-methyl-6-[2-(2,3,6,7-tetrahydro-1H,5H-benzo[ij]quinolizin-9yl)ethenyl]-4H-pyran-4-ylidene] propane-dinitrile}ultrathin layer and 4,4 ´ -bis(2,2 ˊ diphenylvinyl)-1,1 ˊ -biphenyl. It shows a maximum power efficiency of 1.8l m/W at 4 V (the brightness is 51 cd/m2). Its brightness reaches 8496 cd/m2 at 16 V. And the chromaticity coordinates varying from (0.42,0.34) to (0.32,0.28) with the forward bias from 4 to 16 V are well within the white region.

Color Emission

Solid-state luminescent carbon dots (CDs) with visual multiple color emission properties have been prepared by a facile in situ synthesis approach within the confined interlayers of the host 2D matrix LAPONITE® (SNC/Lap). The prospective application of SNC/Lap in white light emitting diode (LED) are demonstrated herein.
