In this paper, Y2O3:Eu3+ nano-phosphor was synthesized through the facile solid-state method and influence of H3BO3 addition to the prepared Y2O3:Eu3+ powder was investigated. The consumption of boric acid resulted in the formation of YBO3 by changing the crystal structure from cubic to hexagonal. Noteworthy, through the use of specific quantities of H3BO3 (medium amount), Y3BO6 impurity with the monoclinic crystal structure and the space group C2/m was formed. FESEM observations showed that the addition of H3BO3 leads to the coarsening of the synthesized particles; changing from approximately 80 nm to 1 ?m. Also, it was concluded that the transformation of the crystal structure causes a dramatic change of phosphor emission colours from reddish to orange.

Herein we report the preparation of a series of Ru(II) complexes featuring alpha-iminopyridine ligands bearing thioether functionality (NNS<sup>R</sup>, where R = Me, CH<sub>2</sub>Ph, Ph). Metallation using (<i>p</i> cymene)RuCl dimer permits access to (k<sup>2</sup>-N,N)Ru complexes in which the thioether moiety remains uncoordinated. In the presence of a strong field ligand such as acetonitrile or triphenylphosphine, the p-cymene moiety is displaced, and the ligand adopts a k<sup>3</sup>-N,N,S binding mode. These complexes are characterized using a combination of solution and solid state methods, including the crystal structure of [(NNS<sup>Me</sup>)Ru(NCMe)<sub>2</sub>Cl]Cl. The k<sup>2</sup>-N,N Ru(II) complexes are shown to serve as efficient precatalysts for the oxidation of sec-phenethyl alcohol at 5 mol% loadings, using a variety of external oxidants and solvents. The complex bearing an S-Ph donor was found to be the most active of those surveyed, suggesting that the thioether donor plays an active role in catalyst speciation for this transformation.
