Herein we report the synthesis and optoelectronic characterisation of three deep blue-emitting cationic iridium complexes, of the form [Ir(dFppy)(2)(N^N)]PF(6), bearing biimidazole-type N^N ancillary ligands (dFppyH = 2-(2,4-difluorophenyl)pyridine). Complex 1 contains the parent biimidazole, biim, while 2 contains a dimethylated analog, dMebiim, and 3 contains an ortho-xylyl-tethered biimidzol...
In this study, a novel photoluminescent quantum dots device with laser-processed microscale patterns has been demonstrated to be used as a white light emitting source. The pulsed laser ablation technique was employed to directly fabricate microscale square holes with nano-ripple structures onto the sapphire substrate of a flip-chip blue light-emitting diode, confining sprayed quantum dots into ...
Fluorescence and, more generally, photoluminescence enable high contrast imaging of targeted regions interest through the use photoluminescent probes with specificity for different targets. can be used rare cell imaging; however, this often requires a space-bandwidth product: simultaneous resolution and large field view. With bulky traditional microscopes, product images require time-consuming ...
Graft polymerization of trimethoxysilyl-containing ammonium cations on negatively-charged titania nanosheets gives a photoluminescent viscoelastic nanocomposite. Proton conduction network comprised of adsorbed water molecules near the titania slabs leads to the multiple conductometric sensitivities to temperature, humidity, and photo-irradiation.
Photoluminescent polymer dots (PDs) were prepared by a moderate hydrothermal treatment of poly(vinyl alcohol) (PVA). A single excited state was established in the PL mechanism by ultrafast spectroscopy. Moreover, the applied method be used to prepare fluorescent polymer dots from other non-conjugated polymers, and shows general universality.
