Two functional Ru(II) mixed-ligand complexes, [Ru(phen)(2)(ttbd)](2+) (1) (ttbd = 4-(6-propenyl-pyrido[3,2-a]phenzain-10-yl-benzene-1,2-diamine, phen = 1,10-phenanthroline) and [Ru(bpy)(2)(ttbd)](2+) (2) (bpy = 2,2'-bipyridine), have been synthesized and characterized. The spectral characteristics of complexes 1 and 2 were investigated using fluorescence(More)
Here, the excellent thermal sensing capability of a multinuclear lanthanide polyoxometalate in the cryogenic region (<100 K) is presented for the first time. Up till now, no lanthanide polyoxometalates have been studied for their use as ratiometric luminescent thermometers. The investigated Tb3+ polyoxometalate cluster is doped with 1.6% (P1) and 8.4% (P2)(More)
Microstructured Y2WO6 materials were prepared in a hydrothermal synthesis in the presence of glycerol, which was employed as both a solvent and a structure directing agent, after which they were heat treated at 1100 °C. These materials, similar to other previously reported Y2WO6 as well as other rare-earth tungstate structures, showed interesting(More)
According to its restriction sites, fragments of 1573 bp, 1197 bp, 896 bp and 795 bp were obtained from the 5' promoter region of wml1 and fused with the coding sequence of the GUS gene. Constructs containing these fragments were introduced into tomato plants via Agrobacterium-mediated transformation. Histochemical assay of GUS expression in transgenic(More)
Uniform mixed CaMoO4-CaWO4 micro-/nano-materials have been successfully synthesised by a facile hydrothermal method. The morphology of these upconversion materials could be changed to different shapes and the size could also be decreased from the micro- to nano-scale by varying the type of surfactant used. It was observed that before heat treatment, the(More)
