In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...

Well-aligned Cu-doped ZnO nanorods were successfully synthesized on polyethylene terephthalate (PET) substrate using chemical bath deposition method. The structural and optical properties of Cu-doped ZnO nanorods were investigated using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX) and photoluminescence (PL) spectroscopy...

We present T-ReCS high spatial resolution N-band (8 − 13 µm) spectroscopy of the central regions (a few kpc) of 3 local LIRGs. The nuclear spectra show deep 9.7 µm silicate absorption feature and the high ionization [S iv]10.5 µm, emission line, consistent with their optical classification as AGN. The two LIRGs with unresolved mid-IR emission do not show PAH emission at 11.3 µm in their nuclear...

cobalt is one of the most important constituent present in ceramic industries. glazers are the relevant workers when they are producing blue colored ceramic, causing occupational exposure to such metal. through this study, urinary cobalt was determined in glazers in a ceramic industry when they were producing blue-colored ceramic glazes.in this case-control study, spot urine samples were collec...

Atmospheric pressure plasma produced by a slot antenna with a pulsed microwave excitation was investigated to understand an electric field influence on hydrogen Balmer- (H) spectral profile using spaceand time-resolved optical emission spectroscopy. Paralleland perpendicular-polarized H emission line profiles with respect to the microwave electric field direction were measured by a polarizat...

We present Gemini spectroscopy for 21 candidate optical counterparts to X-ray sources discovered in the Galactic Bulge Survey (GBS). For the majority of the 21 sources, the optical spectroscopy establishes that they are indeed the likely counterparts. One of the criteria we used for the identification was the presence of an Hα emission line. The spectra of several sources revealed an Hα emissio...

Hexagonal boron nitride is a wide bandgap semiconductor with very high thermal and chemical stability that is used in devices operating under extreme conditions. The growth of high-purity crystals has recently revealed the potential of this material for deep ultraviolet emission, with intense emission around 215 nm. In the last few years, hexagonal boron nitride has been attracting even more at...
