Thermoluminescence study of persistent luminescence materials: Eu(super 2+)- and R(super 3+)-doped calcium aluminates, CaAl2O4:Eu(super 2+),R(super 3+)

Article Abstract:

Thermoluminescence properties of the Eu(super 2+)-, R(super 3+)-doped calcium aluminate materials, CaAl2O4:Eu(super 2+),R(super 3+), are studied above room temperature. The mechanism helps in describing why Na(super +), Sm(super 3+), and Yb(super 3+) suppress the persistent luminescence and other Eu(super 2+)- and R(super 3+)-doped aluminate and silicate materials are studied to confirm the role of the R(super 3+) codoping on the persistent luminescence.

Structure and transport properties of nanostructured materials

Article Abstract:

The simulation of nanoporous aluminum oxide using a molecular-dynamics approach with recently developed dynamic charge-transfer potential using serial/parallel programming techniques is presented. The structure and thermal stability of the nanostructures were investigated, and it was found that the nanoporous hollow spheres have more thermal stability than the porous nanotubes.

High-aspect-ratio aluminum borate nanowire bundles supported by sucrose

Article Abstract:

A novel approach for the growth of the ordered Al(sub 18)B(sub 4)O(sub 33) nanowire bundles is reported, which is synthesized by a sucrose-assisted growth method. Highly viscous polysaccharides of sucrose at high temperatures are responsible for the formation of the nanowire bundles.
