A new cationic Ir(III) complex based on a dendritic ancillary ligand has been designed and synthesized, which simultaneously exhibits piezochromic luminescent (PCL) behavior and aggregation-induced emission (AIE) property for the first time.

The optical response, binding parameters, and duplex DNA binding mode of water-soluble kinetically inert tetranuclear metallomacrocycles can all be controlled by judicious selection of ancillary ligands.

An active one-dimensional Fibonacci photonic quasi-crystal is realized via spin coating. Luminescence properties of an organic dye embedded in the quasi-crystal are studied experimentally and compared to theoretical simulations. The luminescence occurs via the pseudo-bandedge mode and follows the dispersion properties of the Fibonacci crystal. Time resolved luminescence measurement of the activ...

A series of new ligands suitable for the formation of luminescent lanthanide complexes in water is described. The chelates are designed for analyte labeling and play the role of fluorescent donor in homogeneous time-resolved fluorescence assays using LEDs as a light source for excitation at 370 nm. Ligands are constructed from a coumarin nucleus, for lanthanide sensitization, and different amin...

Proteorhodopsins are globally abundant photoproteins found in bacteria in the photic zone of the ocean. Although their function as proton pumps with energy-yielding potential has been demonstrated, the ecological role of proteorhodopsins remains largely unexplored. Here, we report the presence and function of proteorhodopsin in a member of the widespread genus Vibrio, uncovered through whole-ge...

Luminescent carbon-based materials have been prepared by electrostatic self-assembly of negatively-charged luminescent Eu(III)-complex with imidazolium-functionalized MWCNTs.

The color-tunable GdCaAl 3 O 7 : RE 3+ (RE = Eu, Tb, Eu@Tb) phosphors were synthesized via an ultrafast sol-gel auto-combustion synthesis method. X-ray diffraction patterns confirmed the forming of tetragonal phase, and scanning electron microscopy images indicated that obtained products presented honeycomb-like structure due to gas releasing during process. luminescent properties, concentratio...

The emergence of optical Internet Things (optical-IoT) for sixth-generation (6G) networks has been envisaged to relieve the bandwidth congestion in conventional radio frequency (RF) channel, and support ever-increasing number smart devices. Among plethora device innovations deemed essential fortifying development, herein we report on visible-to-near-infrared color-conversion luminescent-dyes ba...

Three-terminal (3T) and four-terminal (4T) tandem photovoltaic (PV) devices using various materials have been increasingly reported in the literature, but measurement standards are lacking. Here, multiterminal measured as functions of two load variables characterized unambiguously three device voltages or currents on hexagonal plots. We demonstrate these techniques GaInP/GaAs solar cells, with ...
