Two phases of the CdTe QDs, namely hexagonal and cubic are confirmed from the HRTEM images and SAED patterns analysis. The phase transformation from hexagonal to cubic is …

2020年1月1日 · Experimental absorption, emission, X-Ray diffraction spectra and electronic band gap have been studied by UV–Vis absorption, luminescence and X-Ray diffraction …

2024年4月3日 · The UV-Vis absorption measurements of CdTe QDs solutions were carried out in a Perkin Elmer spectrophotometer model LAMBDA 1050 UV/Vis/NIR in the 400 to 800 nm region.

2018年6月13日 · The optical properties and band gap energies of CdTe QDs were analyzed using Ultraviolet-visible (UV–vis) spectroscopy (Shimadzu evolution 100) in the 200–800 nm …

2020年4月16日 · UV–vis absorption and fluorescence spectra of l-Cys-CdTe QDs are illustrated in Figure 1(f). Upon illumination at 358 nm, we observe an emission band centered at 562 nm, …

Green, yellow, orange and red CdTe QDs were replaced every day and exposed to daily UV radiation for 12 h for seven consecutive days in summer with UV index signal integration …

1996年7月1日 · In this paper, the photochemical etch technique of CdTe was investigated by using incoherent excimer UV radiation at wavelength 308 nm (XeC1). The electrical properties …

UV exposure causes the release of Cd 2+ ions from the CdTe QD surface. It can be assumed that O 2 molecules oxidize chalcogenide atoms located on the surface of the QDs to form oxides. …

2025年1月13日 · Uniform coverage of CdTe layer on the buffer layer is required for avoiding pin holes and increasing the open-circuit voltage (Voc). The incorporation of dopants play a vital …
