Scientific Interests
Structure, magnetic and optical properties of ordered (crystals, crystalline nanoparticles) and disordered (glasses, compositionally-disordered crystals, solid crystalline solutions, nanocomposite materials) materials. Physics of paramagnetic and luminescence centres in solids, including electron paramagnetic resonance (EPR) and optical spectroscopy of impurity transition and rare-earth ions, as well as intrinsic and radiation-induced defects in oxide compounds with ordered and disordered structures.
Research Focus
Bohdan Volodymyrovych Padlyak specializes in the study of spectroscopic properties and luminescence of various doped glass materials. His research primarily focuses on the impact of different co-dopants, such as silver, manganese, and europium, on the luminescence of lithium tetraborate and other glass systems. He investigates the local structure, magnetic and optical properties, and photoluminescence of materials like Pb-containing germanate and silicate oxyfluoride glasses. His work also extends to the study of paramagnetic centers and intrinsic defects in these materials, contributing significantly to advancements in solid-state physics and optics.
