Synthesis and Characterization of Eu+++Doped Y2O3(Red Phosphor) and Tb+++Doped Y2O3(Green Phosphor) by Hydrothermal Processes

引用

World Journal of Nano Science and Engineering 2012年第1期2卷 13-18页

作者： Ravindra P. Singh Kiran Gupta Ashutosh Pandey Anjana Pandey Department of Chemistry Motilal Nehru National Institute of Technology Allahabad India Nanotechnology and molecular Biology laboratory Centre of Biotechnology University of Allahabad Allahabad India

Eu+++ and Tb+++ doped Y2O3 nanoparticles have been synthesized by hydrothermal process using yttrium oxo-isopropoxide Y5O(OPri)13 as precursor (OPri = isopropxy). X-ray diffraction (XRD), transmission electron microscopy (TEM), nanoparticle size analyzer and photoluminescence (PL) spectroscopy have been used to characterize these powders. The as synthesized powders gave very sharp peak in the X-ray diffraction suggesting crystalline particles with average particle size between 28 - 51 nm for Eu+++ doped Y2O3 nanoparticles and 43 - 51 nm for Tb+++ doped Y2O3 nanoparticles annealed at 300℃ for 3 h, 4 h and 5 h, which could be unique in comparison to other reports. Transmission electron micrograph investigation of the particles shows single dispersed particles along with agglomerates. The ratio of intensities of transitions in the europium and terbium emission spectrum have been used as structural probe to indicate the local environment around Eu+++ and Tb+++ in the Y2O3 particles.

作者：李博文董晨钟蒋军王建国 College of Physics and Electronic Engineering Northwest Normal University Joint laboratory of Atomic and molecular Physics Northwest Normal University & Institute of Modern PhysicsCAS Institute of Applied Physics and Computational Mathematic

A detailed investigation of plasma screening effects on atomic structure and transition properties are presented for He-like ions embedded in dense plasma environment. Multiconfiguration Dirac-Fock calculations were carried out for these ions by considering a Debye-H/ickel potential. A large-scale relativistic configuration sition energies and transition probabilities and interaction method is adopted to calculate tranto allow for a systematic improvement of the calculations. Comparison of the presently calculated results with others, when available, is made

Despite recent progress in crop genomics studies,the genomic changes brought about by modern breeding selection are still poorly understood,thus hampering genomics-assisted breeding,especially in polyploid crops with compound genomes such as common wheat(Triticum aestivum).In this work,we constructed genome resources for the modern elite common wheat variety Aikang 58(AK58).Comparative genomics between AK58 and the landrace cultivar Chinese Spring(CS)shed light on genomic changes that occurred through recent varietal *** also explored subgenome diploidization and divergence in common wheat and developed a homoeologous locus-based genome-wide association study(HGWAS)approach,which was more effective than single homoeolog-based GWAS in unraveling agronomic trait-associated loci.A total of 123 major HGWAs loci were detected using a genetic population derived from AK58 and *** homoeologous haplotypes(HHs),formed by combinations of subgenomic homoeologs of the associated loci,were found in both parents and progeny,and many could substantially improve wheat yield and related *** built a website where users can download genome assembly sequence and annotation data for AK58,perform blast analysis,and run *** work enriches genome resources for wheat,provides new insights into genomic changes during modern wheat improve-.ment,and suggests that efficientmining of elite HHs can make a substantial contribuutionto genomics-assisted breeding in common wheat and other polyploid crops.

We present a systematic investigation of the depolarization properties of a supercontinuum accompanied with femtosecond laser filamentation in barium fluoride(BaF2)*** is found that the depolarization of the supercontinuum depends strongly on the crystal orientations with respect to the incident laser *** most crystal orientations,the depolarization of the supercontinuum rises with the increase of the input laser energies and finally *** at 45°,the depolarization of the supercontinuum is not changed and keeps nearly negligible with the increase of the input laser *** peculiar depolarization properties of the supercontinuum can be ascribed to the orientation dependence of the cross-polarized wave(XPW)generation and ionization-induced plasma scattering in the BaF2 crystal.

investigation of protein-DNA interactions provides important information for understanding gene function and regulation, but identification and validation of specific interactions remain major challenges in the post-genomics era. Therefore, effective and economical methods to assess protein-DNA interactions are highly sought-after by molec- ular biologists.
