Synthesis and luminescence properties of inorganic solid luminescence materials

Luminescence Properties of TeO2-LiF-Gd2O3 Glasses

In this work, the structural properties and spectroscopic behavior 80 mol.%TeO2-20mol.%LiF glasses which were doped with 0. 05, 0. 2 mole% Gd2O3 have been studied. It was shown that,  by increasing the amount of Gd2O3 the glass stability was decreased. The PL emissions at 431nm and 627nm wavelengths were distinguished by 320nm excitation. The FT-IR analysis showed deformed TeO4 groups in these ...

Synthesis and luminescence properties of YF3:Ce3+/Tb3+ nanocrystals.

YF3:Ce3+, YF3:Tb3+, and YF3:Ce3+/Tb3+ nanocrystals were synthesized by an ethylenediaminetetraacetic acid (EDTA)-assisted hydrothermal method and characterized by X-ray diffraction and scanning electron microscope. In the excitation spectra, there is one broad excitation band at 285 nm for YF3:Ce3+ and 255 nm for YF3:Tb3+, which are related to the f-d excitations of the Ce3+ and Tb3+ in the hos...

Synthesis and Luminescence Properties of EuMoO4 Octahedron-Like Microcrystals

Synthesis and Luminescence Properties of Core/Shell ZnS:Mn/ZnO Nanoparticles

In this paper the influence of ZnO shell thickness on the luminescence properties of Mn-doped ZnS nanoparticles is studied. Transmission electron microscopy (TEM) images showed that the average diameter of ZnS:Mn nanoparticles is around 14 nm. The formation of ZnO shells on the surface of ZnS:Mn nanoparticles was confirmed by X-ray diffraction (XRD) patterns, high-resolution TEM (HRTEM) images,...

Experimental Analysis of Luminescence in Printed Materials

This paper is based on a printing industry research project nearing completion [1]. While luminescent pigments have been used for many years, provision of fast response quality control systems have been challenging, primarily due to large and expensive components that are integral to spectroscopy instrumentation. Characteristics of the light sources and detectors used together with application ...
