An intelligent approach to the discovery of luminescent materials using a combinatorial approach combined with Taguchi methodology.

A significant advance made in combinatorial approach research was that the emphasis shifted from simple mixing to intelligent screening, so as to improve the efficiency and accuracy of discovering new materials from a larger number of diverse compositions. In this study, the long-lasting luminescence of SrAl(2)O(4), which is co-doped with Eu(2+), Ce(3+), Dy(3+), Li(+) and H(3)BO(3), was investi...

Synthesis and Luminescent Properties of M 2 V 2 O 7 : Eu ( M 0 Sr , Ba )

A solution combustion route for the synthesis of Eu-activated M2V2O7 (M 0 Sr, Ba) and their luminescent properties have been investigated. Structure and luminescent characteristics of Sr2V2O7:Eu 3+ and Ba2V2O7:Eu 3+ nanophosphors have been studied by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fluorescence spectrometry and Fourier transform infra-red spect...

Luminescence studies on lanthanide ions (Eu, Dy and Tb) doped YAG:Ce nano-phosphors

Yttrium aluminum garnet nanoparticles both undoped and doped with lanthanide ions (Ce, Eu, Dy and Tb) having average size around 30 (73nm) nm were prepared by glycine nitrate combustion method followed by annealing at a relatively low temperature of 800 1C. Increase in the annealing temperature has been found to improve the luminescence intensity and for 1200 1C heated samples there exists stro...

Structural, magnetic and electrical properties of pure and Dy-doped Fe2O3 nanostructures synthesized using chemical thermal decomposition technique

Pure (S1) and Dy3+-doped α-Fe2O3 (S2 and S3) nanoparticles were prepared by a combustion synthesis method at 700 ºC for 8 h using Fe(acac)3 (Tris(acetylacetonato)Iron(III)) as raw material. Characterizations of the prepared powders were carried out by powder X-ray diffraction (PXRD). Structural analysis was performed b...

Preparation of persisted luminescence pigment and investigation of in glaze compatibility

In this paper, preparation of SrAl2O4:Eu,Dy luminescent pigment has been investigated. Coprecipitation as a low cost and facile method was selected. X-ray diffraction patterns indicated the formation of SrAl2O4:Eu,Dy phase through calcinations process above 800 °C. Moreover, a few amount of silica caused the structural transformation to alumina silicate phase. Transparent glaze which consist of...
