The project focuses on the study of tellurite glasses that exhibit high transparency up to the midinfrared region and possess great potential for applications in photonics and optoelectronics, especially in the infrared region. The project focuses on three areas. In the first one, new ternary glasses derived from TeO2-PbCl2 binary: TeO2-PbCl2-Bi2O3/WO3 are prepared and investigated with emphasis on their optical properties and thermal stability. The project also focuses on the study of absorption and photoluminescence (PL) properties of rare earth doped glasses and, with the use of low-temperature PL spectroscopy, on processes of energy exchange between the glass matrix and 4f states of dopants, all this with respect to their potential use as sources and amplifiers in the mid-infrared region. The last area concerns the study of the influence of technological conditions during glass preparation on glass properties and focuses on the methods to increase the optical purity of the prepared glasses, i.e. decreasing of optical losses and improving their PL properties.
