Here, we demonstrate IPES in the near-ultraviolet range ( hν <5eV) using electrons with kinetic energies less than 4eV. The energy resolution of the instrument is attained to be 0.27eV. From the spectra of copper phthalocyanine films, it is found that damage to the organic sample is ...

The Nature of Near-Ultraviolet-selected Objects in the Chandra Deep Field-South* We present the first results of the pure parallel near-UV observations with the Wide Field Planetary Camera 2 (WFPC2) in the Chandra Deep Field-South. The ... DFD Mello,JP Gardner,T Dahlen,... - 《Astrophys...
Enhancement of energy utilization using nanofluid in solar powered membrane distillation. Ten different nanofluids were compared and TiN (titanium nitride) was chosen following UV-Vis-NIR-waveband (ultraviolet-visible-near-infrared) optical ... Yong,Zhang,Lie,... - 《Chemosphere》 被引量: 1发表:...
The absorption coefficient throughout the ultraviolet and near-infrared spectral ranges 0.174–1.8 μm (5555–57,470 cm−1 in wave number) is presented here. CO2 ice samples were grown at a temperature of 150 K, typical of the Martian polar caps. The path length of the samples varied...
Energy Transfer from Sm~(3+) to Eu~(3+) in Red-Emitting Phosphor LaMgAl_(11)O_(19):Sm~(3+), Eu~(3+) for Solar Cells and Near-Ultraviolet White Light-Emitti... Energy transfer from Sm3+ to Eu3+ in red-emitting phosphor LaMgAl11O19:Sm3+, Eu3+ for solar cells and near-...
We investigate the ultraviolet (UV)-light-induced transient photorefractivity in a highly Mg-doped LiNbO[SUB3] crystal. The thermal activation energy of the UV-light-induced defect centers responsible for the induced transient photorefractivity was measured to be 0.65 eV and holes were found to be...

Initially near infrared spectroscopy (NIRS) was used only as an add-on unit to other optical devices, that used other wavelengths such as ultraviolet (UV), visible (Vis), or mid-infrared (MIR) spectrometers. In the 1980s, a single unit, stand-alone NIRS system was made available, but ...
Ultraviolet-blue to near-infrared downconversion of Nd(3+)-Yb(3+) couple To reduce energy losses by thermalization of charge carriers in a silicon solar cell, quantum-cutting luminescent materials are desired for the efficient d... D Chen,Y Yu,H Lin,... - 《Optics Letters》 被引量: 15...
