Organic lanthanides complexes for NIR OLEDs and magnetoresistance investigation

The complexes of f-elements, particularly near-infrared (NIR) emitters are gaining much attention for their potential applications in optical communications, optoelectronic devices and biomedical diagnostic application. The emission from their complexes can be properly utilised in the form of OLEDs. In our laboratories Nd, Yb and Er complexes based on the various fluorinated/non-fluorinated β-diketones and O-donor neutral ligands were synthesised and fully characterised. OLEDs were fabricated and investigated using these complexes as emitting layers along with other organic layers. Moreover, a family of rare-earth quinolinate based complexes, namely tetrakis 8-hydroxyquinolinate (M[RE(q)4], with M=countercation), were used as active layers in the investigation of the spin-orbit coupling in organic magnetoresistance (OMAR) effect. Our measurements in these devices discovered a new feature in the OMAR curves evidencing the influence of the spin-orbit coupling mechanism on charge transport. These results and others will be presented and discussed in this talk.

Symposium CL
Inorganic Materials Systems for Advanced Photonics

The fruitful exploitation of optical ceramics and glasses and related photonic structures and devices as crucial pivots for the development of several enabling technologies provides a large spectrum of functionalities that allow us to face successfully socio- economic challenges in many fields going from energy production and saving to efficient and clean industrial cycles, from environmental protection to fast efficient novel communication systems, from structural monitoring to quantum technologies and to healthcare applications.
This Symposium, that follows the several ones on similar subject held at previous CIMTEC conferences, is to provide latest insights on fabrication, characterization and exploitation of photonic structures based on ceramics (oxides, oxynitrides, fluorides, sulphides, chalcogenides, etc...) inorganic non-metallic glasses, glass- ceramics, and ceramic/metal and glass/metal combinations in the form of nanostructured, bulk and graded materials and coatings, fibres, thin films, superlattices and other small confined systems, nanomaterials, nanocomposites and functional nanoparticles.
Focus will be on theory, modelling and simulation of materials and processes, green and advanced fabrication protocols (self assembly, particle beams, light irradiation, micromachining, colloidal processing...) and up-to-date characterization of structure, non-linear optical properties, tunability, nanosize effects etc. of novel inorganic photonic materials systems for light generation, detection, and manipulation including e.g. luminescent and laser materials, smart optical fibres, active plasmonic heterostructures, novel confined nano-micro structures etc. covering the UHV-IR electromagnetic spectrum.
Contributions from Academia and industry on upgraded or novel application and prospective new approaches to photonic-based technologies are also firmly encouraged.
