Nitrogen-doped β-Ga2O3 nanowires (GaO NWs) were prepared by annealing the as-grown nanowires in an ammonia atmosphere. The optical properties of the nitrogen-doped GaO NWs were studied by measurements of the photoluminescence and phosphorescence decay at the temperature range between 10 and 300 ...
The theoretical spectra accord with the experimental results for transition aB→aB. The stimulated emission characteristic of N molecular dimer was researched through the microwave excited highly pure nitrogen and the method of amplified spontaneous emission. The experimental results show that N molecular ...
1.Observe the emission spectra of various elements and 2.Use the emission spectra to identify the element present Absorption and Emission of Light in a Flame When a substance is heated in a flame, the substance's electrons absorb energy from the flame. This absorbed energy allows the electrons...
The effect of nitrogen (N) doping on the behavior of field emission, surface energy and the band structure of strontium titanate(SrTiO3)thin films coated on silicon tip arrays has been examined in detail. Measurements using x-ray photoelectron spectroscopy, ellipsometry, water contact angle and fi...
We have used the excellent sensitivity of XMM-Newton to obtain the first high-quality X-ray spectrum of a Wolf-Rayet (WR) star which is not known to be a member of a binary system. Our target, the nitrogen-type star WR 110 (= HD 165688) was also observed and detected with the VLA...
Wavelengths below 200 nm are absorbed by some components of air, primarily oxygen and water vapor. Therefore, the usual approach to spectrochemistry in this wavelength region is to evacuate the optical system. The use of a nitrogen gas-filled system provides important advantages for both the indus...
