  • Depth chemical profile in a CeIr3 sample

    Dane Badawcze
    open access

    The polycrystalline sample of CeIr3 used in the present studies was synthesized by arc-melting cerium (4N) and iridium (3N5) in an arc furnace on a water-cooled copper hearth using a tungsten electrode under a high purity argon atmosphere. A piece of zirconium was used as an oxygen getter. First, a button of Ir was prepared by arc-melting the iridium...

  • The luminescence study of Sc2(1–x)Ga2xO3:Cr3+/4+ coumpounds

    Dane Badawcze
    open access

    The growing interest in the use of near-infrared (NIR) radiation for spectroscopy, optical communication, and medical applications spanning both NIR-I (700–900 nm) and NIR-II (900–1700 nm) has driven the need for new NIR light sources. NIR phosphor-converted light-emitting diodes (pc-LEDs) are expected to replace traditional lamps mainly due to their...

  • Dual role of oxygen-related defects in the luminescence kinetics of AlNMn2+

    Dane Badawcze
    open access

    This dataset presents the impact of temperature and pressure on AlN:Mn2+ luminescence kinetics. Unusual behavior of Mn2+ optical properties during UV excitation is observed, where a strong afterglow luminescence of Mn2+ occurs even at low temperatures. When the temperature increases, the contribution of the afterglow luminescence is further enhanced,...

  • Exemplary AFM application in cosmetology

    Dane Badawcze
    open access - seria: Scanning Probe Microscopies data

    Atomic force microscopy can be used in the diagnosis of the condition of human tissues such as skin, nails and hair. This is obviously related to the use of a variety of cosmetic products and can be understood as an attempt to assess their long-term impact on human appearance and health. An example may be the studies presented in [1] indicating the...

  • Imaging of ferroelectric properties of sinter by means of Piezoresponse Force Microscopy

    Dane Badawcze
    open access - seria: Scanning Probe Microscopies data

    Ferroelectricity is a property of certain materials [1], characterized by a spontaneous electrical polarization that can be reversed by applying an external electric field. Ferroelectric properties can be used to make capacitors with adjustable capacity. The permeability of ferroelectrics is not only regulated, but usually also very high, especially...
