A series of new transparent and magnetic barium gallogermanate glasses in the system (x) Gd2O3 – (100-x) [20BaO?15Ga2O3?65GeO2] with x = 0, 8, 14, 18, 22 25 mol% were synthesized. Their thermal, structural properties characterized. Based on differential scanning calorimetry results, one determined composition domain exhibiting highest thermal stability toward crystallization provided a detailed...

Y2O3-stabilized ZrO2 (YSZ) has been the material of choice for thermal barrier coatings (TBCs) in past decades, yet its phase decomposition limits application above 1200 °C. In this study, Gd2O3 and Yb2O3 co-doped YSZ powders were produced, which some amounts monoclinic (m) introduced into cubic (c) matrix. XRD results showed that fabricated obtained by a solid synthesis composed m c phases, ha...

There is great technological interest in elucidating the effect of particle size on the luminescence efficiency of doped rare earth oxides. This study demonstrates unambiguously that there is a size effect and that it is not dependent on the calcination temperature. The Y₂O₃:Eu and Gd₂O₃:Eu particles used in this study were synthesized using wet chemistry to produce particles ranging in size be...

Nanoprobes for combined optical and magnetic resonance imaging have tremendous potential in early cancer diagnosis. Gold nanoparticles (AuNPs) co-doped with Gd2O3 mesoporous silica nanocomposite (Au/Gd@MCM-41) can produce pronounced contrast enhancement for T1 weighted image in magnetic resonance imaging (MRI). Here, we show the remarkably high sensitivity of Au/Gd@MCM-41 to the human poorly di...

Hyperspectral microscopy is an intriguing technique combining spectroscopy with optical that can be used to simultaneously obtain spectral and spatial information. The relevance of hyperspectral imaging in biomedical applications such as the monitoring bioimaging agents, identification pathogens cancerous cells, cellular uptake nanoparticles has emerged recently, due recent advances reconstruct...
