The luminescence properties of Eu(2+) doped strontium aluminates are reported and reviewed for a variety of aluminates, viz. SrAl12O19, SrAl4O7, Sr4Al14O25, SrAl2O4 and Sr3Al2O6. The aim of the research is to investigate the role of local coordination and covalency of the aluminate host lattice, related to the Sr/Al ratio, on the optical properties of the Eu(2+) ion. The UV and VUV excited lumi...

Ceramic composites based on alumina and zirconia have found a wide field of application in the present century orthopedic joint replacements, their use dentistry is spreading. The development this class bioceramic was started 1980s, but first clinical applications total hip replacement were introduced market only early 2000s. Since then, several composite systems replacements. These materials a...

A variety of novel phenomena and functionalities emerge from lowering the dimensionality materials enriching degrees freedom in modulation. In this work, it is found that saturation magnetization LaMnO3 (LMO) films largely enhanced by 56% after releasing a brand-new phase tetragonal strontium aluminate buffer layer, significantly increased 92% with bending to curvature 1 mm−1 using water-assist...

Three types of solvents with different polarity (cyclohexane, toluene and benzene), a nonionic surfactant Span 40 were used to prepare strontium aluminate (SrAl2O4) spinel nanoparticles by a reverse micelle method. The structure of SrAl2O4 nanoparticles was characterized by X-ray diffraction (XRD). The morphology and size of the synthesized materials were studied using field emission scanning e...

Nanosized copper aluminate (CuAl(2)O(4)) spinel particles have been prepared by a precursor approach with the aid of ultrasound radiation. Mono-phasic copper aluminate with a crystallite diameter of 17nm along the (311) plane was formed when the products were synthesized using Cu(NO(3))(2) x 6H(2)O and Al(NO(3))(3) x 9H(2)O as starting materials, with urea as a precipitation agent at a concentr...
