A triphenylamine derivative as an efficient organic light color-conversion material for white LEDs
Journal of Luminescence, 2008Abstract A novel efficient (Φ=0.44) organic yellow-emitting dye, 3-(4-(diphenylamino)phenyl)-1-phenylprop-2-en-1-one (DPPO), was synthesized. The compound was characterized by means of 1H NMR and differential scanning calorimetry (DSC) and analyzed by quantum chemistry method.

We report a simple and easy method to fabricate silica nanotubes (SNTs) with multicolor up-conversion luminescence by single-nozzle electrospinning based on phase separation effect without any templates. Multicolor up-conversion nanoparticles (UCNPs) were first synthesized by a similar hydrothermal route.

Solid Confinement of Quantum Dots in ZIF‐8 for Efficient and Stable Color‐Conversion White LEDs
ChemSusChem, 2017AbstractThe powder form and low photoluminescence quantum yield (PLQY) of fluorescent metal–organic frameworks (MOFs) present a serious obstacle to fabricating high‐efficiency film‐like lighting devices. Here, we present a facile way to produce thin films of CdSexS1−x/ZnS quantum dots (QDs)@ZIF‐8 with high PLQY by encapsulating red, green, and blue ...
