Electron Paramagnetic Resonance (EPR) is a technique applied in several areas of science, from dosimetry, structural determination of proteins and free radical generation studies, and also acts as a very efficient technique when it comes to the study of paramagnetic species. In the study of luminescent phenomena, it can be used for the determination of ionic species involved in luminescen…
This proposal aims to develop new micro and nanostructured luminescent materials based on ra-earth ions (TR:Sc, Y, La-Lu) with applications in the energy area, health, telecommunication, radiation detection, and safety. Different strategies will be undertaken to develop new luminescent materials focused on the energy converter area, such as i) Molecular light-converting devices through th…

Nanoscintillators have recently been extensively studied for various applications, such as X-ray detection, correlative bioimaging, X-ray-induced photodynamic therapy, information encoding, among others. The possibility of converting X-rays into radiation in the UV-Vis-IR region is the property that makes scintillators interesting materials, and synthesizing them in the form of nanomateri…
In this project, plasmonic gold and silver nanoparticles functionalized with trivalent lanthanide ion coordination compounds (Ln3+) will be developed. The main objective is to investigate the potential of these new nanomaterials as optical markers in biological assays, seeking to improve sensitivity and selectivity in detection. Recent studies demonstrate that the coupling between plasmon…

Lanthanide beta-diketonate complexes have been known for a long time in both tris and tetrakis forms. These complexes present characteristic 4f-4f emission of the Ln3+ ion even when the excitation is at the ligand absorption due to the intramolecular energy transfer processes. While the theoretical model for the energy transfer is already well stablished, few experimental techniques are a…
Materials that exhibit the phenomenon of persistent luminescence are capable of emitting light for more than 24 hours after a source of radiation has ceased on it. Its long time of emission is explained by the storage of excitation energy in defects of the crystalline network (called traps). This energy is released gradually, with the advent of the thermal energy present in the environmen…
The luminescent materials MAl2O4:Eu2+,TR3+ (M = Ca, Sr, Ba), (TR = Nd3+,Dy3+) belongs to the class of the alkaline earths aluminates doped with rare earth ions, they present persistent luminescent properties, emitting light for several hours after removed the excitation source. This phosphors display low chemical stability when in contact with water. It results in the total suppression of…

The development of new inorganic persistent luminescent materials containing rare earthions as activators is more than ever a reality, allowing the emergence of innovative and improved solid-state lasers, biological and forensic markers, thermal sensors, security devices, and other several products in photonic technology areas. In this context, Stannate-based host matrices have attracted …
The understanding of intramolecular energy transfer processes in lanthanide coordination compounds is of utmost importance for the development of numerous fields of application such as: sensors, safety markers, OLEDs, nanothermometers etc. In this context, the transient absorption technique is an extremely powerful technique to probe the "ligand-character" non-emitting levels such as the …
The development of organic light emitting diodes (OLEDs) attracts interest due to their potential application in electroluminescent devices for full-color flat panel displays and television screens. Materials that present the possibility of color tuning can be applied for instance to produce different light emitting materials, including white emitters. However, obtaining efficient hosts t…
