Biomimetic humidity sensors offer a low-power approach for respiratory monitoring in early lung-disease diagnosis. However, balancing miniaturization and energy efficiency remains challenging. This study addresses this issue by introducing bioinspired humidity-sensing neuron comprising self-assembled peptide nanowire (NW) memristor with unique proton-coupled ion transport. The proposed shows low Ag
A simple and feasible method was used to fabricate the optical temperature probe. point all-fiber sensor built based on up-conversion emission spectra of Er<sup>3+</sup>/Yb<sup>3+</sup> co-doped NaYF<sub>4</sub> phosphors.
An emission-tunable, Eu2+-activated, Ba2Ca(PO4)2:Eu2+ phosphor was synthesized by a conventional solid-state reaction. X-ray powder diffraction (XRD) and FT-IR spectroscopic analysis confirmed the phase formation. Electron paramagnetic resonance (EPR) indicated there are three different crystallographic Ba2+ sites, namely, Ba(1), Ba(2) Ba(3), occupied Eu2+ ions. The excitation emission spectra, concentration dependence of intensity decay curves were investigated. results showed that with...

Novel rare earth doped glass ceramics containing NaY(WO4)2 nanocrystals were fabricated for the first time. The appearance of sharp diffraction peaks and well-resolved lattice fringes certifies precipitation with high crystallinity. After crystallization process, significant changes in photoluminescence emission spectra fluorescence lifetime Sm3+ ions are observed, which ascribable to enrichment highly disordered nanocrystals. Under 980 nm excitation, characteristic green red upconversion...
