The Bi 2 S 3 /SnS heterostructure was synthesized and used as a bifunctional gas-sensing material through visible light modulation; it is ultrasensitive to NO under irradiation but highly selective H in the dark.
Tin disulfide (SnS2) has been extensively researched as a promising sensing material due to its large electronegativity, suitable band gap, earth abundance, and nontoxicity. However, the poor conductivity slow response/recovery speed at room temperature greatly hinder application in high-performance practical gas sensors. Herein, promote study of SnS2-based sensors, hierarchical SnS2/TiO2 heterostructure was synthesized used detect NO2 with help light illumination. Through synergistic effect...
Heterostructure construction is an effective strategy for enhancing the properties of functional materials.
Hexagonal-phase NaYF 4 : Yb 3+ , Er nanoparticles (NPs) have been widely used as the most efficient NIR-to-visible upconversion (UC) luminescent and probe in bioscience.Here, we exploited not only function of dual-mode emission β-NaYF NPs near infrared (NIR) visible regions with single wavelength excitation at 980 nm, but also physiological temperature sensing luminescence region.The structural optical characteristics were obtained using X-ray diffraction (XRD), scanning electron microscopy...
Carbon-doping mediated synergistic effect of energy-band modification and vacancy provides a new solution for developing high-performance LMDs-based gas sensors.
Nanosheet-assembled hierarchical SnSe 2 could serve as a new suitable candidate for high-performance room-temperature NO gas sensing.
The upper limit of Tm<sup>3+</sup> doping concentration increases from the well accepted 0.5% to 3% in NaGdF<sub>4</sub>@Yb/Tm:NaGdF<sub>4</sub> NCs with an inert-core/active-shell structure, and UC intensity about 6 times, benefiting enhanced energy transfer efficiency Yb<sup>3+</sup> ions by confining them a two-dimensional space.
The design of novel nanoparticles with higher therapeutic efficacy and lower side effects, is still difficult but encouraging in cancer therapy. Specifically, for upconversion (UCNP)-based drug release, a high intensity NIR light (1.4~5.0 W/cm
Upconversion luminescence properties were investigated by emission intensity<italic>vs.</italic>excitation power (double logarithmic relationship) and temperature dependent spectroscopy.
2D/2D van der Waals (vdW) heterostructure is an effective strategy for improving the functions of 2D layered nanomaterials due to high-quality heterointerfaces with lacked dangling bonds at interfaces. However, little attention was paid investigating effect heterointerface amount and quality on gas-sensing performance. Here, two sets SnS2/SnSe2 vdW heterostructures tunable SnSe2 content are fabricated by physical mixing solvothermal growth methods room-temperature NO2 gas sensors. Compared...
Understanding the relationship between sensing behavior and energy level is an important prerequisite for providing rational guidance to predict advanced gas-sensing materials develop design principles. A tunably compositional van der Waals (vdW) alloy SnS1-xSex (x=0.2, 0.4, 0.6, 0.8) that reveals trend of response value with Fermi first reported here, which prepared by isoelectronic Se atoms substituting S SnS via ion exchange method. The cause-and-effect disclosed Kelvin probe force...
