Chemically and thermally stable lanthanide-doped Y2O3 nanoparticles for remote temperature sensing in catalytic environments

Lanthanide-Doped Nanoparticles for Diagnostic Sensing

Lanthanide-doped nanoparticles exhibit unique optical properties, such as a long luminescence lifetime (up to several milliseconds), sharp emission peaks, and upconversion luminescence over the range of wavelengths from near-infrared to visible. Exploiting these optical properties, lanthanide-doped nanoparticles have been widely utilized for cellular and small animal imaging with the absence of...

Lanthanide - doped upconversion nanoparticles

Enhancing luminescence in lanthanide-doped upconversion nanoparticles.

The enthusiasm for research on lanthanide-doped upconversion nanoparticles is driven by both a fundamental interest in the optical properties of lanthanides embedded in different host lattices and their promise for broad applications ranging from biological imaging to photodynamic therapy. Despite the considerable progress made in the past decade, the field of upconversion nanoparticles has bee...

Remote Sensing for Marine and Coastal Environments

A scanning lidar system provides high-resolution two-dimensional measurements of ocean wave displacement. The airborne operation further enhances the speed of data acquisition. These properties allow rapid characterization of the ocean wave environment. In addition to active ranging, the scanning optics can obtain passive measurements of surface emissivity, yielding a digital image of the surfa...

USE OF PURE AND SULPHUR DOPED TiO2 NANOPARTICLES FOR HIGH TEMPERATURE CATALYTIC DESTRUCTION OF H2S GAS

H2S reduction over Pure and Sulphur doped TiO2 nanoparticles was studied in this work. The parameter was catalytic destruction of H2S gas under high temperature of 450C using fixed bed catalytic system under laboratory conditions. Under these conditions 99.97% reduction was achieved using S-doped TiO2. 2.89% Sulphur was adsorbed on S-doped TiO2 nanoparticles to form Ti(SO4)2. Comparatively, no ...
