Additional recruitment to the Doctoral School of Exact Sciences beyond the limit of places

Project description:   

The main goal of the proposed scientific project is to develop the novel, contactless, nondestructive and relatively cheap methods of detection of the pressure- or/and temperature-induced structural phase transitions in optical inorganic materials doped with lanthanide ions (Ln3+), e.g., Pr3+, Nd3+, Sm3+, Eu3+, Dy3+, Ho3+, Tm3+, etc. Exceptional luminescence properties of lanthanide ions, especially their hypersensitive radiative transitions, which depend on the local symmetry of the Ln3+ and surrounding of the ions in the crystal structure, make them promising candidates for such purposes internal change structure sensor. The change of physical parameters such as  temperature and pressure may have significant influence on the structural changes of the matrices doped with Ln3+ ions, which causes specific changes in photophysical properties of Ln3+ ions i.e., changes in emission, excitation and absorption spectra. Alterations in both spectroscopic and structural properties will be recorded at high pressure (101-102 GPa) and high temperature (from 300 K to above 800 K). The next stage of the research will be correlation of spectroscopic properties with changes in the internal structure of materials under extreme conditions of high pressure (HP) and high temperature (HT). In the case of optical materials with plastic deformations of the structure, i.e., exhibiting irreversible phase transformations may result in the development of new, stable materials with unique properties, such as permanently enhanced luminescence or improved sensing performance. On the other hand, materials with elastic transformation of the structure will show reversible changes of structural and spectroscopic properties useful for sensing applications.

The next goal of this scientific project is related to the scaled-up synthesis of the novel materials formed under extreme conditions. In other words, based on the obtained results from the mentioned irreversible transformation of materials under extreme conditions, the large scale synthesis process of new materials with novel properties will be done with the use of hydraulic press up to 10 GPa, and furnace up to 1600 K. It allow to obtain materials up to several grams per one compression or heating process, what is thousands of times more efficient process than compression of materials in a diamond anvil cell (DAC) or heating of the materials on heating stage. The plans proposed in this scientific project results in synthesis and investigation of new optical inorganic materials  doped with Ln3+ ions, that can be applied as novel light sources or light converters and can have profound implications for the development of next-generation electronic devices, sensors, and photonic technologies.

Last goal is associated with the previously mentioned research of reversible phase transitions, and it is a development of novel HP and HT optical sensors i.e., optical manometers and thermometers based on the reversible luminescence properties change e.g., spectral shift or varied luminescence intensity ratio.
