Particles employed for this purpose have been,e.g., metals (gold, silver), transition metal oxides (polyoxometalates, titanium oxides) or coordination compounds (Prussian Blue, Ruthenium Purple). Importantly, the color of nanoparticles, in particular of metal particles, can depend on their sizes ...
The color of your basement ceiling may not be the first thing on your mind when designing your basement space, but it plays a crucial role in the overall aesthetics and functionality of the area. Whether you’re looking to create a cozy home theater, a stylish home office, or a vibrant ...
Zinc sulfide, the only product that can be used in glass formulas, is short as well, hampering the production of glass compounds across the plastics industry. Even if COVID-19 subsides and pigment and additive availability returns to normal, supply chain challenges are likely to persist well ...
The coordination symmetry of the surrounding anions is significant to the degeneracy of the activator 5d level in the 4f → 5d transition shown below because the Tb activators are not in a perfect octahedral crystal-field environment. As heterovalent and homovalent substitutions, the PLE and PL ...
The affinity between the polymer phase and yellow colorants in coffee is responsible for the absorption and penetration of the colorants into the organic phase of the resin-based materials. This phenomenon could be attributed to various staining compounds present in coffee, including gallic acid, ...
(Fig.4d, e, respectively). Moreover, the Stokes shift observed with compound 1 was larger than with both compounds 2 and 3 in the presence of γ-CD (Supplementary Figs.30and31). No increase in the long wavelength emission was detected upon the addition of excess α-CD or β-CD (...
Devices containing Ce3+-based compounds as emitting layers are uncommon. In some cases, Ce3+ is used to excite other compounds [42] or to improve the efficiency of the devices [43,44]. Su and coworkers [45] isolated and used the complex [Ce(1c)2]3+, doped in MADN (MADN, 2-me...
Moreover, selective changes in luminescence behavior are observed on treating the guest@MOF samples with volatile organic compounds (methanol, acetone and toluene), indicating that these host–guest systems have potential applications as fluorescence sensors. It can be expected that by rational selection...
This invention relates to improved imaging systems based on the formation of yellow colored coordination compounds of transition metals with certain ligands. These coordination compounds have been found to provide excellent yellow colors when used in pressure sensitive carbonless copy-papers wherein the im...
In a particularly preferred embodiment, the ionically complexed black colorant compound contains no polymeric components. Such a compound is of particular benefit because it is easier to assure full coordination of all ionic sites when reacting only monomeric materials. Thus, larger compounds may have...
