Fluorescence lifetime was successfully used aa a monitor for the purity of solid fluoranthene purified by several different methods; i.e., sublimation in vacuo, zone refining, a newly developed chemical process, and the chemical process followed by zone refining. The spectral response of the life...
For instance, p-shell excitation scheme has been shown to lead to exceptionally high purity of single-photon emission28. Additionally, like any anomalous behavior, it states an interesting basic research problem. Such an inverted dependence forms a gap in, seemingly nearly complete nowadays, ...
Ions with energies in the range of a few keV up to hundreds of keV implant in the coatings, and the profile of the implantation distribution is dependent on the thin film density. Previous studies of low-energy He ion irradiation in metals, such as W, Au, and Cu, demonstrate the formati...
Article: Investigation of mass dependence effects for the accurate determination of molybdenum isotope amount ratios by MC-ICP-MS using synthetic i
The optical constants (n, k) and the thickness (t) of the films were determined from optical transmittance data, in the spectral range 500–2500 nm, using the Swanepoel method. The dispersion parameters were determined from the analysis of the refractive index. An analysis of the ...
The correction factors depend on s due to the change of the spectral shape and reach 2 %, 4 % and 6.5 % at s=0.9, 2.76 and 7 TeV for the highest p T. The systematic uncertainty of the momentum scale is |Δ(p T)/p T|<0.01 at p T=50 GeV/c, as determined from the mass ...
This variation is due to a number of intrinsic factors (excitation cross section, photon and electron reflection and refraction, inelastic processes, etc.) as well as instrumental factors (monochromator transmission and spectral purity, electron analyzer transmission and resolution, etc.). In this ...
LC-tuned voltage controlled oscillators (LC VCOs) are widely used in high performance phase locked loops (PLLs) and frequency synthesizers due to their high spectral purity. The oscillation frequency of an LC VCO is commonly assumed to be the resonant frequency of the LC tank. However, this ...
spectral linewidthIn this paper, we investigate the temperature dependence of spectral linewidth of InAs/InP quantum dot distributed feedback lasers. In comparison with their quantum well counterparts, results show that quantum dot lasers have spectral linewidths rather insensitive to the temperature with...
The spectral dependence of fluorescence lifetimes was measured with benzo[ g,h,i]perylene of extremely high purity (<10 −6 mole/mole perylene as an impurity), the result showing that the fluorescence consists of two regions with different lifetimes. This means that the sample still contains ...
