Fluorescence intensity ratio-based temperature sensing with a self-referencing characteristic is highly demanded for reliable and accurate sensing. Although enormous efforts have been devoted to explore high-performance luminescent probes, it remains daunting challenge achieve relative sensitivity which determines resolution. Herein, we employ novel strategy probes ultrahigh through integrating both positive negative thermal quenching effect into hydrogel. Specifically, Er3+ ions show...
Abstract The conventional sea water desalination technologies are not yet adopted worldwide, especially in the third world countries due to their high capital cost as well large energy requirement. To solve this issue a sustainable way an interfacial solar evaporation device is designed and proposed article using branches of Prunus serrulata (PB). PB has abundant microchannels shows excellent photothermal conversion capability after carbonization. Moreover, easy access raw materials facile...
A red-emitting phosphor, Eu2+-activated Ca4(PO4)2O phosphor was synthesized by conventional solid-state reaction. X-ray powder diffraction confirmed the phase formation. The band gap of estimated to be about 4.75 eV from diffuse reflection spectrum. excitation and emission spectra, concentration dependence intensity were investigated. results showed that under at 460 nm, Ca4(PO4)2O:Eu2+ phosphors exhibit strong red centered 665 optimum Eu2+ in is 0.07 mol per Ca2+ ions. nature ion...
Although single metal atoms (SMAs) have been extensively investigated as unique active sites in single-atom catalysts, the possible of host catalysts unfortunately neglected previous studies. In SMAs can promote chemical and catalytic activities atoms, which may act secondary sites, resulting a significant synergistic effect on performance. Using density functional theory calculations, we studied oxygen evolution reaction (OER) reduction (ORR) two different types sites: (M1) neighboring...
We demonstrate a mode-locked all-fiber Tm laser using single mode-step index multimode-graded-index multimode-single mode fiber structure as saturable absorber based on the nonlinear multimodal interference.
