Journal ArticleDOI
Optical properties of rare-earth doped epitaxial Sr0.5Ba0.5Nb2O6 thin films grown by pulsed laser deposition
TL;DR: In this paper, the authors show that the photoluminescence (PL) spectra of RE-doped SBN ceramics show a strong and broad emission band at around 600 nm (2.07 eV).
Journal ArticleDOI
Efficient doping and energy transfer from ZnO to Eu3+ ions in Eu(3+)-doped ZnO nanocrystals.

TL;DR: The result indicates that Eu3+ ion-doped ZnO nanocrystals are promising light-conversion materials and have potential application in highly distinguishable emissive flat panel display and LED backlights.
Journal ArticleDOI
Synthesis and luminescence of a novel conjugated europium complex with 6-paramethylaniline carbonyl 2-pyridine carboxylate
Bao-Li An,Bao-Li An,Kok Wai Cheah,Wai-Kwok Wong,Jianxin Shi,Jianxin Shi,Ning-sheng Xu,Yan-sheng Yang,Menglian Gong,Menglian Gong +9 more
TL;DR: A novel organic ligand, 6-paramethylaniline carbonyl 2-pyridine carboxylic acid (Hp-MAP), and the corresponding europium complex, tris(6paramethylinear methylene carboxylato (THC)-carboxylate carboxymethylato (Eu-p-map), were designed and synthesized using time-resolved spectroscopic analysis as discussed by the authors.
Journal ArticleDOI
Characterization of Superfine Sr2CeO4 Powder Prepared by Microemulsion-Heating Method
TL;DR: In this article, the powder of the Sr 2 CeO 4 is prepared by microemulsion-heating method and a film of the phosphor on ITO glass is formed by electrophoretic deposition.
Journal ArticleDOI
Blue-shift and intensity enhancement of photoluminescence in lead-zirconate-titanate-doped silica nanocomposites.
TL;DR: These studies demonstrate the typical quantum size effect of ferroelectric-doped nanocomposites and the large influence of the silica matrix on the PL intensity of the embedded PZT particles.
