Photoluminescence properties of Eu3+ doped BaF2 nanomaterials and BaF2:3Eu/Fe3O4 nanocomposite for hyperthermia application

Eu3+ activated BaF2 nanostructured thin films: fabrication and a combined experimental and computational study of the energy conversion process

“…In fact, due to the forbidden nature of their 4f-4f intraconfigurational transitions, the lanthanide ion emissions show long decay times (micro-or even milliseconds), increasing the chances of sequential excitations and energy transfers populating the excited energy levels. 7 Eu 3+ ions have attracted great attention from the scientific community, thanks to the long decay times of the mainly emitting 5 D 0 excited state, related to the typical red emission at around 615 nm, making it attractive for applications in nanothermometry, 8 biomedicine, 9 and, recently, also in photovoltaics as a luminescent dopant in inorganic matrices for DC processes. 10,11 Actually, it has been demonstrated that fluoride hosts, compared to other inorganic ones, such as metal oxides, are more efficient for energy conversion processes.…”
