“…This results in five upconverted luminescence bands at wavelengths 390, 410, 525, 540 and 650 nm (Fig. 6), which were attributed to 4 [27]. It is important to mention that Yb 3+ being sensitizer absorbs the NIR radiation and transfers to closely lying proximal Er 3+ ions present in the NaYF 4 lattice, resulting in characteristic upconversion emission (Fig.…”

“…Hydrothermal method has been a popular [24][25][26] technique for thin-film deposition on various substrates, for example, deposition of Sb 2 S 3 on indium tin oxide [27], high quality nanocrystalline CdZnS film on plain glass slide [28] and β-LaS 2 on stainless steel [29]. Also, the hydrothermal process is simple to use and enables the formation of highly crystalline films, with potential for large scale preparations, in a fewer number of steps as compared to other techniques [30][31][32].…”

We report simultaneous crystal growth and deposition of upconverting Yb3+/Er3+ doped NaYF4 film (UCF) on conducting and non-conducting substrates by one-step hydrothermal method. The characteristics such as film topography, morphology, crystallographic phase and upconverting luminescence intensity were found to depend both on the chelating agent and nature of the substrate. The characteristics of the prepared films varied interestingly when either the chelating agent or the substrate was changed. The upconversion emission intensities were found to increase with decreasing film roughness. Further, current investigation demonstrated that the NaYF4 films deposited using EDTA or DTPA chelating agents on ITO substrate and EGTA chelating agent on PG substrate were more uniform and resulted in greater upconverted emission intensities. We envision plausible use of current technology in the development of affordable optical platforms for several optoelectronic applications.

“…The crystalline structure and the purity of the samples prepared at different PVP amounts were characterized by XRD technique. As shown in figure 1, the XRD patterns of all the samples synthesized with the addition of PVP can be identified as monoclinic WO and the -NH + groups originated from the protonation of N in PVP during the aging in acidic medium [30]. However, h-WO 3 was obtained when no PVP was added into the reaction system, which can be easily seen from the pattern in figure 1(a): the characteristic peaks of h-WO 3 [31].…”

Nanoparticles of monoclinic WO3 were synthesized by a facile method using Na2WO4 as raw material and PVP 70 000 (polyvinylpyrrolidone) as surfactant and template. The effect of PVP on the structure and photocatalytic activity of the synthesized WO3 was discussed in detail. The prepared samples were characterized by XRD, SEM, FT-IR, UV–vis, XPS, PL techniques, and the results show that the visible light is strongly absorbed by the obtained samples, whose particle size varies from 38 to 85 nm. The photocatalytic properties of the resulted samples were evaluated using RhB in water as a target substance, and results illustrate that 30 mg l−1 of RhB can be efficiently photodegraded by nano WO3 under visible light irradiation. Based on the results of XPS, PL and photocalysis experiments, the reason of such improved photocatalytic efficiency may be attributed to the reducing activity of PVP, which leads to the formation of oxygen vacancies beneficial for the capture of photoelectrons and the generation of superoxide radicals. Furthermore, the results show that the photocatalytic efficiency is greatly influenced by the morphology of the synthesized WO3 samples, and the WO3 with a block-shaped morphology is an ideal photocatalyst for the degradation of RhB under visible light irradiation.

“…These Sb 2 S 3 nanostructures exhibited photoelectronic properties in an indium tin oxide (ITO)/Sb 2 S 3 /ITO model device, namely, a fast temporal photoresponse and photoswitch capability. Orthorhombic Sb 2 S 3 can be prepared by various methods such as the solvothermal method, [ 276,277 ] liquid exfoliation, [ 278,279 ] and electrochemical lithium intercalation. [ 280 ] The Sb 2 S 3 nanosheets can be grown directly on graphene with enhanced catalytic properties owing to the synergism of the superior conductivity of graphene and the 2D nanostructures of Sb2S3.…”

2D materials based on main group element compounds have recently attracted significant attention because of their rich stoichiometric ratios and structure motifs. This review focuses on the phases in various 2D binary materials including III-VI, IV-VI, V-VI, III-V, IV-V, and V-V materials. Reducing 3D materials to 2D introduces confinement and surface effects as well as stabilizes unstable 3D phases in their 2D form. Their crystal structures, stability, preparation, and applications are summarized based on theoretical predictions and experimental explorations. Moreover, various properties of 2D materials, such as ferroelectric effect, anisotropic optical and electrical properties, ultralow thermal conductivity, and topological state are discussed. Finally, a few perspectives and an outlook are given to inspire readers toward exploring 2D materials with new phases and properties.
