The Group of the High-Pressure Spectroscopy ON 4.1 specializes in spectroscopic studies of optical materials in ambient and extreme conditions including high pressures, cryogenic and high temperatures. For pressure-dependent studies, diamond anvil cells (DAC) are used, allowing pressures of up to about 30 MPa at temperatures down to 4 K. Studies are being conducted on crystalline...

Research

New phosphor materials emitting in deep red and near-infrared (NIR) regions based on oxide crystals doped with transition metal ions such as Cr3+, Mn4+ or Fe3+ for applications as non-contact luminescent temperature and pressure sensors or biological markers. Studies of oxide phosphors doped with bismuth ions aimed to clarify the nature of Bi3+ ion emission occurring in these compounds in...
