Luminescence Excitation Spectra and Their Exciton Structures of ZnS Phosphors. I. Mn, (Cu, Al), (Ag, Al) and (Au, Al) Doped Phosphors

Teruhiko Hoshina、H. Kawai1980-02-01Japanese Journal of Applied Physics

Single-ion luminescence due to Mn 2+ and donor-acceptor pair luminescence due to (Cu, Al), (Ag, Al) and (Au, Al) centered in hexagonal ZnS have been investigated at 75 K with a major focus on exciton structures in the excitation spectra. Appearance of exciton peaks in Mn 2+ luminescence excitation spectra indicates th…

Effect of hydrolysis and drying on the siloxane bonds of a silane coupling agent deposited on E‐glass fibers

Hatsuo Ishida、Jack L. Koenig1980-02-01Journal of Polymer Science Polymer Physics Edition

Abstract Molecular structural changes of a vinyl functional silane coupling agent on E ‐glass fibers, induced during the immersion test in hot water, have been studied using Fourier transform infrared spectroscopy. The amount of the coupling agent on the glass fibers is reduced by hydrolytic degradation. Silanol group…

MECHANICAL PROPERTIES AND LOCOMOTOR FUNCTIONS OF EEL SKIN

Mary Reidy Hebrank1980-02-01Biological Bulletin

1. The skin of the American eel Anguilla rostrata is composed largely of a crossed-helical array of fibers, believed to be collagen, that are oriented at an angle of 45° with the long axis of the fish. Uniaxial and biaxial tension testing of eel skin was used to assess the role of the collagen fibers in the locomotor…

Mössbauer studies of hydrogen absorption in Dy, DyMn_{2}, DyFe_{2}, DyCo_{2}, and DyNi_{2}

Rachel Cohen、K. W. West、F. W. Oliver 等 4 位作者1980-02-01Physical review. B, Condensed matter

The M\"ossbauer effect has been used to study hydrogen absorption in Dy, Dy${\mathrm{Ni}}_{2}$, Dy${\mathrm{Co}}_{2}$, Dy${\mathrm{Mn}}_{2}$, and Dy${\mathrm{Fe}}_{2}$. Isomer shifts in the hydrides of the intermetallics are similar to those found in the dysprosium hydrides. Measurements at 4.2 K for the hydrides of t…

Correlation of mechanical and electrical losses in ferroelectric ceramics

P. Gerthsen、Karl Heinz Härdtl、N. A. Schmidt1980-02-01Journal of Applied Physics

The correlation between electrical and mechanical losses in ferroelectric ceramics has been investigated theoretically and experimentally. The theoretical derivation is based on the assumption that both loss types are induced by 90° domain walls moving under the influence of electrical or mechanical fields. A proporti…

Impact ionization rates for electrons and holes in Ga0.47In0.53As

T. P. Pearsall1980-02-01Applied Physics Letters

We report the determination of the impact ionization rates for holes and electrons in Ga0.47In0.53As with the electric field oriented in the 〈100〉 direction. Our measurements show that the ionization rate for electrons α is greater than that for holes (β) by about a factor of 2 over electric fields ranging from 2.0×10…
