ZrO2 is an attractive host matrix for luminescence material because of its excellent physical properties, such as low phonon energy and wide band gap. In this work, the highly transparent Tm2O3 Yb2O3 co-doped yttria stabilized zirconia (YSZ) (abbreviated Yb/Tm: YSZ) single crystals were grown by optical floating zone method. The YSZ samples in cubic phase at room temperature when Yb3+ Tm3+ repl...

Rapid deactivation presently limits a wide spread use of high-temperature solid oxide cells (SOCs) as otherwise highly efficient chemical energy converters. With triggered by the ongoing conversion reactions, an atomic-scale understanding active triple-phase boundary between electrolyte, electrode, and gas phase is essential to increase cell performance. Here, multi-method approach used compris...

A novel route to fabricate nano-fiber anode material for solid oxide fuel cells (SOFCs) is presented. Firstly, uniform nano-fibers of 8 mol % Yttria Stabilized Zirconia (8YSZ) were formed in an electrospinning process; then, these electrospun fibers were calcined at temperatures up to 1300 °C; and finally the ceramic 8YSZ nano-fibers were coated with nickel in an electroless plating process. Th...

Yttria-stabilized zirconia (YSZ) is a widely recognized ceramic of distinct electrical, mechanical and optical properties. Although YSZ an intrinsically paramagnetic solid, it could potentially transform to magnetic semiconductor by incorporating in its crystalline structure isolated atoms bearing unpaired valence electrons. Based on this hypothesis motivated the latest advances doped with rare...

This study focused on the numerical simulation of distribution residual stress in yttria-stabilized zirconia (YSZ) coatings prepared with atmospheric plasma spraying (APS). We particularly investigated around interface between top coat and bond coat. During thermal spray deposition, droplets particles deposit substrate a complex manner, causing waviness non-uniform distribution. Therefore, is a...

A novel procedure to make self-supporting thin yttria-stabilised zirconia (YSZ) membranes by laser machining is shown. We have used a galvanometric controlled laser beam to machine the surface of a conventional sintered YSZ plate and achieved thin areas up to 10 lm thick, but also maintaining thicker support beams to ensure the structural strength of the membrane. The outer areas of the plate a...

In this study, (Gd0.9Yb0.1)2Zr2O7 (GYbZ)/yttria-stabilized zirconia (YSZ) double-ceramic-layer (DCL) thermal barrier coatings (TBCs) were prepared by plasma spray-physical vapor deposition (PS-PVD). The microstructure, mechanical performance, and shock behavior of with spraying distances 600, 800, 1000 mm investigated. GYbZ coating a distance 600 showed closely packed columnar structure. Howeve...

The redox behavior of terbium and praseodymium doped yttria-stabilized zirconia (YSZ) is studied. aim to identify spectroscopic probes a suitable experimental procedure monitor the oxygen activity in YSZ electrolytes solid oxide cells with spatial resolution at operation conditions (e.g. high temperatures). Sintered ceramics crystals 0.3 10 at% content Pr or Tb ions were prepared. Upon equilibr...
