Published 2000Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The dependence of the fluorescence lifetime of the 4S3/2 state of the Er3+ ion on the ErF3 concentration was measured in fluorozirconate glasses at room temperature. Energy transfer rates were calculated from optical parameters assuming that the Er3+ ions in fluorozirconate glasses were dispersed as the cubic, bcc, or fcc structure, and were inserted into the rate equation. The dependence of the total transition rate of the 4S3/2 state of the Er3+ ion on the ErF3 concentration was calculated by using the rate equation and compared with the total transition rate measured by the lifetime experiment. Although many studies have reported the energy transfer rates in various rare-earth ions, the reliability of the calculated energy transfer rates has been hardly discussed. The energy transfer rate can be derived from the total transition rate. The energy transfer rate estimated from the rate equation calculation was compared with the energy transfer rate obtained from the lifetime measurement. It could be shown that the calculated energy transfer rate assuming that the Er3+ ions were dispersed as the cubic structure was closer to the measured energy transfer rate than that as the bcc and fcc structures. With increasing the ErF3 concentration, the calculated energy transfer rate when the Er3+ ions were dispersed as the cubic structure was comparable to the measured energy transfer rate. It was suggested that at the lower concentration of ErF3 (≤2 mol %), we needed to use the distance between Er3+ ions which was shorter than that as the cubic structure in the calculation of the energy transfer rate. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The upconversion emission intensities of Er3+ ion around 550 and 660 nm in fluorozirconate glasses were measured under 800 nm excitation. Though energy transfer processes played an important role in upconversion mechanism at high concentration of ErF3, those have not been treated quantitatively. The energy transfer rates were calculated from the optical parameters assuming some distribution of Er3+ ions. We calculated the upconversion intensities around 550 and 660 nm by using rate equations. It was found that the dependence of upconversion emission intensities on the ErF3 concentration could be reproducible and the principal upconversion mechanism could be evaluated. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We have fabricated resonant tunneling structures having a buried ErAs semimetallic quantum well and AlAs double barriers, on (001)GaAs substrates. In order to suppress the three-dimensional island growth of GaAs and AlAs on ErAs and to obtain flat interfaces, we adopted a template approach, in which one monolayer of Mn was deposited on ErAs prior to the growth of AlAs, in molecular beam epitaxy. In the current–voltage characteristics at room temperature, negative differential resistance was clearly observed in a significant number of diodes with the ErAs thickness ranging from 2.6 to 5.0 nm. This room-temperature device operation on (001) substrates is, we believe, an important step towards the realization of semimetal/semiconductor hybrid quantum devices. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Er3+ singly- and Er3+/Yb3+-codoped fluorozirconate glasses were prepared. The upconversion emission intensities of the Er3+ ion around both 550 and 660 nm were measured under 800 nm excitation. The absorption band of the Yb3+ ion is located around 980 nm. Though the absorption band of Yb3+ does not interact directly with the incident light at 800 nm, both upconversion intensities around 550 and 660 nm emission increased with the increasing YbF3 concentration. We calculated the upconversion intensities around 550 and 660 nm by using rate equations and evaluated the principal upconversion mechanism in Er3+ singly- and Er3+/Yb3+-codoped samples quantitatively. We also investigated the reason for the increase of the upconversion emission intensities with the codoping of Yb3+ under 800 nm excitation. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Peripheral blood neutrophils from germ-free (GF), specific-pathogen-free (SPF) and conventional (CV) rats were compared. Besides neutropenia and impaired superoxide anion generation as previously reported, it was found that GF rats had lower phagocytic function (70%) and generated less nitric oxide than the other rats. GF and SPF rats were injected with recombinant human granulocyte–colony-stimulating factor (rhG-CSF), or were transferred to natural environment. It was found that total number, phagocytosis, intracellular killing, ratio of phagocytosis versus killing (killing efficiency) and nitric oxide production induced by recombinant rat interferon-γ (rrIFN-γ) were normalized upon injection of rhG-CSF. These results indicate that rhG-CSF may stimulate neutrophil production and induce the expression of neutrophil receptors for phagocytosis and nitric oxide production in GF rats. Although lower than in CV rats, the level of superoxide produced was sufficient for normal neutrophil-killing efficiency in SPF and GF rats. In SPF rats, this could be amended by exposure to natural environment. However, neither rhG-CSF injection nor transfer to natural environment could increase the generation of superoxide anion in GF rats.Type of Medium: Electronic ResourceURL: -
