The near and mid-infrared spectra, which corresponds to the vibrational resonances of chemical bonds, holds substantial significance in various technological domains, particularly in sensing applications. Furthermore, the 3-5 ¼m and 8-14 ¼m atmospheric transparency windows enhance its practical applicability. Optical fibers, due to their extended interaction length, offer a promising phot…
Materials that exhibit persistent luminescence (PersL) can be characterized by their ability to absorb light from an excitation source and slowly release it as luminescence over a long period of time. Classic examples of their application include emergency signaling. The discovery of new efficient, size modulated, and different emission regions, has enabled their use in various fields suc…
This research proposal aims to develop new and efficient glass and glass-ceramic materials based on lanthanide-doped tellurite and fluorotellurite, that can act in the areas of photonic materials, light energy converters, and luminescent temperature sensors. The proposal focuses on the spectroscopic studies of these inorganic materials with efficient emission in the visible and near-infra…
The project focuses on the study, synthesis, and characterization of tellurite and fluorophosphate glasses containing chalcogenide quantum dots (QDs), possessing high potentiality for photonic and optoelectronic applications from visible to near infrared. Three main steps will be taken to implement the project. In the first, new tellurite and fluorophosphate glasses will be investigated e…
The mitigation of greenhouse gas emissions to sustainable levels is critical since they affect air quality and global warming. Several efforts are made to develop efficient and precise detectors to mitigate these gas emissions. This research project aims to create an advanced greenhouse gas sensor employing OH-free tellurite glasses doped with rare-earth ions. The first step of this proje…
Metal-organic frameworks (MOFs) represent a class of materials that has received increasing attention since their discovery, mainly because of the large surface area presented by these materials due to the permanent porosity acquired by their structure. Various applications have been discovered for these structures, such as gas storage, separation of molecules, catalysis, photonics, drug …
Volatile Organic Compounds (VOCs) are organic compounds with vapor pressures exceeding 0.01 kPa at 293.15 K, originating from both natural sources and human activities. Monitoring VOC emissions is crucial to prevent environmental degradation, and to protect people against health hazards such as carcinogenic risks and potential explosions. However, Brazil currently lacks specific legislati…

Exhaled air (consisting of gases, VOCs, and aqueous microgots), has been an important matrix for the detection of lung diseases, for instance, Covid-19. However, in the biochemical processes that occur in the body during the onset or disappearance of a disease, gases and VOCs can be emitted, which can move from the blood into the lung alveoli, and thus they be detected in the exhaled air.…
The main objective of the project is the study of fluorophosphoniobate glasses obtained from sodium metaphosphate (NaPO3) combined with earth-alkali metal fluorides XF2 (X = Mg, Ca, Sr, Ba) and Nb2O5. Glasses with molar composition (80-y)NaPO3-(20)XF2 -(y) Nb2O5 will be obtained by the melt-cooling method and characterized as to their structural, optical, luminescent and thermal propertie…
Glasses are versatile materials in composition and structure, which allow various applications from ornaments to complex waveguides and sensors. Its high demand in telecommunications applications is related to its interactions with electromagnetic waves, thus light.

This proposal aims to design and evaluate a dual-mode optical gas sensor based on a dual-channel integrated hollow waveguide (iHWG) system for detecting volatile organic compounds (VOCs) relevant to medical diagnostics. The sensor will combine direct absorption in the mid-infrared (MIR) region or UV in one channel, with indirect photoluminescence detection in the second channel from iHWG,…
Fiber optic-based sensors have become a promising platform for the development of remote chemical sensing solutions, allowing in-situ and faster responses. These devices are continuously evolving and new methods of improving their performance are constantly being developed, such as the use of a chemosensing agent to generate or enhance the signal to be detected. In this regard, lanthanide…
The proposed research project for the research exchange program abroad encompasses advanced structural and spectroscopic exploration of both the glass materials already synthesized in the ongoing study under the scholarship in the home country, with molar compositions of 80-yNaPO3-20XF¬2-yNb2O5 and 99,5[80-yNaPO3-20XF¬2-yNb2O5]:0,5%Eu2O3, and the newly proposed glass matrix codoped with t…
Optical fibers have been used for many applications due to their features like immunity to electrical interference, miniaturization, bending flexibility, remote and on-time acquisition of data for inaccessible locations or harsh environments. In general, optical fibers are used in sensing to guide the signal to the detectors. However, in the last few years, chemical and physical modificat…
