New insights in the structure-luminescence relationship of Eu:SrAl2O4
Elsevier (2009)This work aims the preparation of Eu:SrAl2O4 through a sol-gel methodology. Some studies point out the possibility that hexagonal polymorph exhibit higher luminescence efficiency than the monoclinic one. However, the slow ... -
Optical characterisation and photothermal conversion efficiency of a water-based carbon nanofluid for direct solar absorption applications.
Elsevier (2020-12-01)Carbon nanoparticles are very useful in solar thermal applications as they absorb much of the solar spectrum and can be inexpensive. Water-based carbon nanofluids with two different concentrations (3 and 33 mg l−1) were ... -
Optoelectronic Properties of Excitonic and Biexcitonic Complexes in Metal Chalcogenide Semiconductor Nanoplatelets
Universitat Jaume I (2022-11-14)Nanoplatelets (NPLs) are of particular interest for their unique properties, they have a precisely controlled thickness of a few atomic monolayers (MLs), and lateral dimensions ranging from hundreds of nm to few nms, where ... -
Quantum mechanical modeling of excited electronic states and their relationship to cathodoluminescence of BaZrO3
American Institute of Physics (AIP Publishing LLC) (2013)First-principles calculations set the comprehension over performance of novel cathodoluminescence (CL) properties of BaZrO3 prepared through microwave-assisted hydrothermal. Ground (singlet, s*) and excited (singlet s** ... -
