A high spectral resolution investigation of diffuse interstellar bands (DIBs) in the near-infrared ($YJ$ band) is conducted to test new methods, confirm and improve existing parameters, search for DIBs. Methods: The CRyogenic high-resolution InfraRed Echelle Spectrograph (CRIRES) on European Southern Observatory's Very Large Telescope was employed obtain spectra four reddened background supergi...
background and objective: multi-walled carbon nano tubes (mwcnts) as an important element of nanosciences have a remarkable absorption in the region of nir window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. to disperse mwcnts in water, it is proposed to attach carboxylated functional group (-cooh) to mwcnts in order to increase dispersivity in wate...
Here, we show that solution-processed Cu-Sn-S semiconductor nanocrystals (NCs) demonstrate a tunable localized surface plasmon resonance band in the near infrared region, where strong saturable absorption occurs. A saturable absorber based on these plasmonic NCs enables the construction of a stable mode-locked femtosecond fiber laser operating at the telecommunication band.
We present the optical identifications and a multi-band catalogue of a sample of 478 X-ray sources detected in the XMM–Newton and Chandra surveys of the central 0.6 deg of the ELAIS-S1 field. The most likely optical/infrared counterpart of each X-ray source was identified using the chance coincidence probability in the R and IRAC 3.6 μm bands. This method was complemented by the precise positio...
