We investigate the effect of synthesized time on the structure, as well as optical properties in ZnWO4 nano rod prepared by hydrothermal method. The prepared rods were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman scattering, absorption and photoluminescent (PL) spectra techniques. The size and morphology of ZnWO4 nano-rod can be controlled by adjusting the...

Excimer laser pulsed deposition was applied to the deposition of organic thin ®lms on sapphire and on glass. The thin ®lms were analyzed by X-ray diffraction (XRD), micro-Raman spectroscopy and ESCA. It was found that the properties of the ®lms were very close to that of the target materials. Strong photoluminescence was observed for both Alq3 and N,N 0-diphenyl-N,N 0-bis(3-methylphenyl)-(1,1 0...

Ce doped Sr2Y8(SiO4)6O2 translucent ceramics were successfully fabricated by spark plasma sintering and their photoluminescent properties were studied in correlation with the crystal structure. There are two crystallographic sites A and A for Ce in the Sr2Y8(SiO4)6O2 host and according to the analysis of the photoluminescence spectra, the energy levels of Ce at A and A sites were demonstrated b...

Using commercially activated carbon, we developed a simple and effective direct chemical oxidation route to prepare good biocompatible multicolor photoluminescent carbon dots.

Correction for 'Highly photoluminescent copper carbene complexes based on prompt rather than delayed fluorescence' by Alexander S. Romanov et al., Chem. Commun., 2016, 52, 6379-6382.

A photoluminescent three-dimensional coordination polymer containing two types of cavities is prepared by the covalent linkage of 2D bilayer motif with linear connecting ligand.

Herein, a label-free multiplex photoluminescent silicon nanoprobe (PLSN-probe) is introduced as a potential substitute for quantum dots (QDs) in bioimaging. An inherently non-photoluminescent silicon substrate is altered to create the PLSN-probe, to overcome the major drawbacks of presently available QDs. Additionally, crystallinity alterations of the multiplane crystalline PLSN-probes lead to ...

Multifunctional Fe3O4/Eu(DBM)3phen/PVP ((DBM: dibenzoylmethane, phen: 1,10-phenanthroline, PVP: polyvinyl pyrrolidone) microfibers were constructed by simple electrospinning process. The structure and morphology of the characterized X-ray diffraction (XRD), scanning electron microscopy (SEM) transmission (TEM) images. diameters pure PVP doped only with Fe3O4 nanoparticles (NPs) uniformly distri...

this paper deals with evaluating the thermal behavior of exterior walls in dwellings of a particular place. today, there is a huge increase in constructing multi-storey apartment buildings and single-family houses in the city of yazd, a city with hot dry climate and a rich historical architecture in iran. unfortunately, the new methods that are used nowadays to make the envelopes of these dwell...
