Influence of fluorescent pigments on the spectral characteristics of luminous coated fabrics

open access: yesMaterials Research Express, 2021
In recent years, luminous coated fabrics based on SrAl _2 O _4 : Eu ^2+ , Dy ^3+ luminescent materials have attracted more attention. However, due to the single emission color of SrAl _2 O _4 : Eu ^2+ , Dy ^3+ luminescent materials, the application of ...

Evidence for Atmospheric Cold-trap Processes in the Noninverted Emission Spectrum of Kepler-13Ab Using HST/WFC3 [PDF]

open access: yes, 2016
We observed two eclipses of the Kepler-13A planetary system, on UT 2014 April 28 and UT 2014 October 13, in the near-infrared using Wide Field Camera 3 on the Hubble Space Telescope.

Ultra-narrow room-temperature emission from single CsPbBr3 perovskite quantum dots

open access: yesNature Communications, 2022
Semiconductor quantum dots have long been considered artificial atoms, but despite the overarching analogies in the strong energy-level quantization and the single-photon emission capability, their emission spectrum is far broader than typical atomic ...

NEAR-INFRARED EMISSION SPECTRUM OF WASP-103B USING HUBBLE SPACE TELESCOPE/WIDE FIELD CAMERA 3 [PDF]

open access: yes, 2016
We present here our observations and analysis of the dayside emission spectrum of the hot Jupiter WASP-103b. We observed WASP-103b during secondary eclipse using two visits of the Hubble Space Telescope with the G141 grism on Wide Field Camera 3 in ...

THE SPECTRUM OF ISOTROPIC DIFFUSE GAMMA-RAY EMISSION BETWEEN 100 MeV AND 820 GeV [PDF]

open access: yesAstrophysical Journal, 2014
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a residual all-sky emission component commonly called the isotropic diffuse γ ...

Energy Spectrum of Acoustic Emission Signals in Complex Media [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
A model of the energy spectrum of acoustic emission signals in complex structures with internal degrees of freedom is proposed. On the basis of the computational experiment of X-ray diffraction data, a quantum mechanical calculation of the applicability ...

The Binary Neutron Star Event LIGO/Virgo GW170817 160 Days after Merger: Synchrotron Emission across the Electromagnetic Spectrum [PDF]

open access: yes, 2018
We report deep Chandra X-ray Observatory (CXO), Hubble Space Telescope (HST), and Karl J. Jansky Very Large Array (VLA) observations of the binary neutron star event GW170817 at t < 160 days after merger.

In Situ Spectroscopic Analysis of the Carbothermal Reduction Process of Iron Oxides during Microwave Irradiation

open access: yesMetals, 2018
The effects of microwave plasma induction and reduction on the promotion of the carbothermal reduction of iron oxides (α-Fe2O3, γ-Fe2O3, and Fe3O4) are investigated using in situ emission spectroscopy measurements during 2.45 GHz microwave processing ...

Planck Intermediate Results. IX. Detection of the Galactic haze with Planck [PDF]

open access: yes, 2012
Using precise full-sky observations from Planck, and applying several methods of component separation, we identify and characterize the emission from the Galactic "haze" at microwave wavelengths.

Real-time emission spectrum from a hybrid atom-optomechanical cavity [PDF]

open access: yes, 2015
We theoretically investigate the real-time emission spectrum of a two-level atom coupled to an optomechanical cavity (OMC). Using the quantum trajectory approach, we obtain the single-photon time-dependent spectrum in this hybrid system where the ...
