Sn-doped ZnO nanocrystalline thin films with enhanced linear and nonlinear optical properties for optoelectronic applications

Structural, electrical, and nonlinear optical performance of PVAL embedded with Li+‐ions for multifunctional devices

“…The direct refractive index n ( λ ) can be calculated as follows n ( λ ) is defined as: n AV ( λ ) > > n 2 ( λ ), n ( λ ) = n AV ( λ ) and ( E 2 ) is mean square values of electric field. χ (1) can be known from the following equation 49,50 : The third‐order nonlinear optical susceptibility ( χ (3) ) follows the relation 51 : From Equations (9) and (10), we get the following equation: where A is given by 1.7 × 10 −10 esu 51 . Thus, n 2 can be obtained from the below equation: The linear ( χ (1) ) and third‐order (χ (3) ) susceptibilities, as denotes in Table 2, tend to increase with increasing the LiNO 3 in the PVAL.…”

The role of cobalt doping in tuning the band gap, surface morphology and third-order optical nonlinearities of ZnO nanostructures for NLO device applications

“…The optical and the NLO properties of ZnO thin lms can be tuned by appropriate dopants. [9][10][11] The inuence of Co into the host ZnO, the size of the nanocrystals were varied and could be the conducting layers for numerous applications such as solar cells and transparent display devices 12 In particular, Zn 1Àx Co x O as a TCO lm exhibits numerous advantages over ITO since both Zn and O are abundant and non-toxic elements. 13 Several deposition techniques such as chemical vapor deposition, 14 magnetron sputtering, 15 pulsed-laser deposition, 16 atomic-layer deposition, 17 sol-gel 18 and spray pyrolysis 19 have been used to prepare ZnO lms.…”

Photopolymerized Films with ZnO and Doped ZnO Particles Used as Efficient Photocatalysts in Malachite Green Dye Decomposition

“…On the other hand, significant peak shifts could be observed for the ZnO-SnO 2 sample as compared to the pure ZnO, changes that are probably caused by the appearance of heterostructures between the ZnO and SnO 2 . For this sample, the peaks were found at 71, 404, 667, and 580 cm −1 , the last one characteristic for ZnO being in the form of a small shoulder [47,48]. The peak at 667 cm −1 could be associated with the oxygen vacancies of SnO 2 nanocrystal surface defects [55,56].…”

“…Considering this, our current research was focused on the development of ZnO doped with tin dioxide (SnO 2 ), another inorganic material broadly used in photocatalysis due to its photosensitivity, transparency, and chemical stability. SnO 2 has excellent properties, such as chemical and thermal stabilities, and found applications in dye-sensitized solar cells [43], photocatalyst [44], gas sensors [45], and so on [46][47][48]. In this study, the doping of ZnO particles with Sn ions was carried out by a chemical process, and their physicochemical characteristics were thoroughly explored; the purpose of this doping was to make structural modifications and the possibility to use these particles in simulated solar light photodegradation experiments.…”
