Magnetische Suszeptibilität der flüssigen B-Elemente

From experimental data of the magnetic susceptibilityχ for various B-elements (Tab. 2 and 3) the contributionχ _e from electrons of the outer shell has been derived. Theχ _e-values of theliquid B-elements are found to be distributed systematically in the periodic table (Tab. 4). Most of these values can readily be interpreted by simplified theories (Larmor-Langevin-term for non-metallic, Pauli-Landau-term offree electrons for metallic melts). Some complicated cases (e.g. liquid Te) can be explained by considering the chemical bond. Besidesχ _e, the temperature dependency of the susceptibility and its change by melting are discussed in detail (Tab. 6 and 7).

Elektrophotolumineszenz eines Zink-Cadmium-Sulfid-Phosphors in Abhängigkeit von Anregungswellenlänge und Feldimpulsbreite

Luminescence flashes in an excited ZnCdS (Ag) phosphor occur when electric fields are put on or off. Whether these flashes are positive or negative depends on the length of the field pulse, on the exciting wavelength, and on the polarity of the irradiated electrode. There is a critical duration of the field pulses for which no field-off flash appears. At another but related critical time, the flashes with periodic field applications change sign. These times change with the exciting wavelength. The observations are interpreted as being controlled by the gradual filling of surface traps, which in its turn is influenced by the distribution of electron and hole concentrations produced by the incident radiation and the electric field. The critical time is approximately equal to the time needed for completely filling the surface traps.
