Luminescent materials are of great interest for a variety of optical applications including new display technologies and lasers. A number of inorganic compounds doped with lanthanides trivalent ions are known to exhibit interesting luminescent properties. We are investigating the preparation of luminescent inorganic nanoparticles coated with organic surfactants with the objective of incorporati...

Studies of metal nanocluster (M-NCs)-based sensors for specific analyte detection have achieved significant progress in recent decades. Ultra-small-size (<2 nm) M-NCs consist of several to a few hundred metal atoms and exhibit extraordinary physical and chemical properties. Similar to organic molecules, M-NCs display absorption and emission properties via electronic transitions between energy l...

wileyonlinelibrary.com to authenticate are therefore important for the protection of brands and valuable documents such as bank notes, diplomas and certifi cates. Luminescent tags or labels are appreciated security elements for protecting authenticatable articles. One way to incorporate luminescent materials as luminescent security elements is to print them with luminescent inks. [ 2 ] Nowadays...

The synthesis, structure, and properties of six luminescent pyridylpyrrolide complexes and the first structural characterization of pyridylpyrrolide metal complexes are reported. A series of new zinc complexes, bis(pyridylpyrrolyl)zinc, (R2PyrPy)2Zn (R = Me, Et, iPr, tBu, and Ph), that vary in their substituents on the pyrrole ring (Me, Et, iPr, tBu, and Ph), were prepared. Pyrrole substitution...

This perspective describes the survey of family mechanochromic luminescent cubane copper iodide clusters. Studies their luminescence properties are presented along with investigations to elucidate underlying mechanism.

Nanocrystalline Zinc Oxide (ZnO) powders with different morphology have been successfully synthesized by using different surfactants such as Cetyl Trimethyl Ammonium Bromide (CTAB), Sodium Dodecyl Sulphate (SDS), and Tri Ethanol Amine (TEA) via hydrothermal method. The products were characterized by means of powder X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electr...
