“…As a dopant, tin serves as a model probe atom to permit local structure changes characterization of the impurity in chalcogenide glass. [93][94][95][96][97][98][99][100][101][102][103][104] For example, doping of a high concentration of Sn in the As-Se system causes an increase in the growth of the tetrahedral unit of structure Sn(Se 1/2 ) 4 . 93 Tin as an impurity signicantly inuences the absorption edge, causing the exponential slope to decrease, widening the spectral range of photoconductivity, and delaying the recombination of the photogenerated holes.…”

In this work, we demonstrated that thermal-annealed (GaIn)2O3 films deposited by sputtering can be used for UV detector applications. X-ray diffractometer measurement shows that the (GaIn)2O3 film annealed at 900 °C possesses the best crystal orientation. All annealed (GaIn)2O3 films have a high transmittance of over 80% in the visible light region measured by a spectrometer. The photoresponse of the (GaIn)2O3 film-based photodetectors was affected by the annealing temperature. A film annealed at 800 °C possesses high photosensitivity (2.5 × 104), high photoresponsivity (16.9 A/W), as well as high detectivity (3.11 × 1011 Hz1/2 W–1) at 5 V bias under 254 nm illumination. The photoresponsivity has been improved through thermal annealing. However, further increasing the annealing temperature from 700 to 1100 °C decreased the photoresponsivity. The decay/rise time reduced obviously after thermal annealing. Both the variation of photoresponsivity and response time should concern with the variation of oxygen vacancies. This work is helpful for the preparation of a (GaIn)2O3-based ultraviolet photodetector and the improvement of its response speed and responsivity.

In this paper, we reported the extraction process of five different flowering plants utilizing different dye extraction methods and solvents (ethanol and water) to choose the best dye removal process. The FTIR spectra revealed the presence of several clear functional groups for all five natural dyes. The analytical studies such as UV spectroscopy, column chromatography, and vacuum evaporation were performed to isolate the dyes from their solutions. The UV-Vis studies on the pigments of flower extracts indicated broad absorption peaks in the visible region including clear bandgaps. Among the studied pigments, Alternanthera ficoidea showed the lowest direct bandgap of 1.69 eV and an Urbach energy value of 6.33 meV. The dye extraction yield rate improvement was extended from 11.7 to 24.7% (water solvent) and 11.3-32.4% (ethanol solvent). Throughout the studies, it was observed that ethanol produced a better extraction for organic dyes than water as a solvent. Aging studies revealed that all the dyes at the room temperature showed better stability with minor changes in the observed optical parameters in oxygen-rich conditions; however, these parameters have shown significant variations at a 60 C temperature.
