Nitrogen-Doped Carbon Dots Induced Enhancement in CO2 Sensing Response From ZnO–Porous Silicon Hybrid Structure

“…Although their origin is still controversial, yellow-red emissions have been related to the formation of oxygen interstitials (O i ) in ZnO (Escobedo-Morales and Pal, 2008;Ahn et al, 2009;Morales Flores et al, 2014), and their presence can be correlated with the thermal treatment conditions during the preparation of the ZnO-pSi hybrid structures. The deconvolution of the NCD-ZnO-pSi-1 PL spectrum (Figure 4B) revealed the presence of one additional emission band at 2.36 (525 nm), which has been widely related to the formation of oxygen vacancies (V O ) in different metallic oxides, including ZnO (Leiter et al, 2003;Escobedo-Morales and Pal, 2008;Ahn et al, 2009;Bitenc et al, 2009;Morales Flores et al, 2014;León Sanchez et al, 2015;Ramos Ramón et al, 2018). As observed in the proposed bands diagram (Figure 4C), the emissions in between 2.18 and 2.54 eV are caused by defect-defect transitions (Escobedo-Morales and Pal, 2008).…”

Dielectric Properties of Aqueous Electrolyte Solutions Confined in Silica Nanopore: Molecular Simulation vs. Continuum-Based Models

“…Meanwhile, the arrangement of water molecules is constrained by the space and modulated by the potential field of microstructure of the cavity wall, resulting in a colorful order degree and phase structure of confined aqueous system [3][4][5]. The local polarization ability of interfacial water molecules also affects the interactions between water molecules and other charged particles, thus affecting many important physicochemical-processes of interfacial water such as surface hydration [6][7][8], ionic solvation [9][10][11][12], and nanofiltration (NF) mass transfer process [13,14]. During the last decade, the main applications in NF have been in water treatment for drinking water production (including ground and surface water) as well as wastewater treatment.…”
