Preparation and Properties of Co-Doped ZnO Nanowires

Spintronics aims at developing a new generation of electronic materials for consumer products based on electron spin rather than on electron charge. Its main objective is the fabrication of new devices based on semiconductor materials with magnetic behavior (so called diluted magnetic semiconductors). These devices combine the manipulation of electrons as classically known in semiconductor devi...

Phosphor-Doped Thermal Barrier Coatings Deposited by Air Plasma Spray for In-Depth Temperature Sensing

Yttria-stabilized zirconia (YSZ)-based thermal barrier coating (TBC) has been integrated with thermographic phosphors through air plasma spray (APS) for in-depth; non-contact temperature sensing. This coating consisted of a thin layer of Dy-doped YSZ (about 40 µm) on the bottom and a regular YSZ layer with a thickness up to 300 µm on top. A measurement system has been established; which include...

Mn4+-Doped Magnesium Titanate—A Promising Phosphor for Self-Referenced Optical Temperature Sensing

Phosphors based on magnesium titanate activated with Mn 4 + ions are of great interest because, when excited with blue light, they display a strong red-emitting luminescence. They are characterized by a luminescence decay which is strongly temperature dependent in the range from -50 ∘ C to 150 ∘ C, making these materials very promising for temperature sensing in the biochemical field. In this w...

Structure and Photoluminescence Properties of Sm3+ Ion-Doped YInGe2O7 Phosphor

A new phosphor, Sm3+ ion-doped YInGe₂O₇, was synthesized using a planetary ball mill solid state reaction. The XRD patterns show that all of the peaks can be attributed to the monoclinic YInGe₂O7 crystal structure when the Sm3+ ion concentration is increased up to 20 mol %. Under an excitation wavelength of 404 nm, the Sm3+ intra-4f transition appears in the emission spectrum including two stro...

Magnetic Properties of Fe Doped, Co Doped, and Fe+Co Co-Doped ZnO

The structural, electronic and magnetic properties of Zn0.95Co0.05O, Zn0.95Fe0.05O and Zn0.90Fe0.05Co0.05O nanoparticles prepared by a sol-gel method are presented and discussed. Xray diffraction and optical analysis indicated that high spin Co ions substitute for the Zn ions in tetrahedral sites. Fe Mössbauer spectroscopy showed the presence of isolated paramagnetic Fe ions in both Fe doped an...
