The Rare Earths (RE), which have been a topic of research and of personal satisfaction for more than 55 years (ORQUIMA, 1961), are present in almost all activities of everyday life. This project consist in four of their more relevant subjects in development at the Rare Earths Laboratory (LTR). We search the evolution of the synthetic procedures, characterization and potencial application…
The Rare Earths (RE), which have been a topic of research and of personal satisfaction for exact 50 years (ORQUIMA, 1961) are present in almost all activities of the everyday life. In this project, we present three of their most relevant applications that are part of the research topics developed at the Rare Earth Laboratory (LTR). First, this project aims at developing phosphors for avoi…

Recovery of rare earth elements (RE) in exhausted fluorescent lamps using non-aggressive and environmentally sustainable methods to recover RE present in the phosphoric powder of the lamps followed by some separation and purification steps.
Although the sun is essential for life on Earth, it can cause a lot of damages to health because of the ultraviolet radiation (UV) that is part of its light. To avoid the health damage caused for exposure to ultraviolet radiation, it is necessary the use of UV filters to act as barrier.Cerium phosphates have already been tested and showed great results as UV absorber but the synthesis met…
The objective of this project is the achievement of new nanostructured materials with zinc, titanium and cerium oxides, aiming at a fine control of the morphology, structure and composition. In this sense, after the development of appropriate synthesis methodologies, the correlations between the structural characteristics and optoelectronics properties will be investigated. In addition, w…

Rare earth-based compounds are well known for being used in several application fields, with a notorious importance in the elaboration of luminescent materials. Particularly, luminescent inorganic nanoparticles containing rare earths are highly promising systems for the development of new technologies in illumination and visualisation devices, as well as in biological labelling. In this s…
Cerium, zinc and titanium oxides show high ultraviolet absorption intensity, due this fact new systems based on these oxides are very important in the photochemical process. Once they can be applied to use solar energy for technological development acting since heterogeneous photocatalysis to photovoltaic systems; the aim is to obtain cerium:zonc:titanium oxides systems with finely contro…
