In situ and continuous monitoring of thermal effects is essential for understanding photo-induced catalytic processes at catalyst's surfaces. However, existing techniques are largely unable to capture the rapidly changing temperatures occurring in sub-μm layers liquid-solid interfaces exposed light. To address this, a sensing system based on gold-coated conventional single-mode optical fiber with tilted Bragg grating inscribed core proposed demonstrated. The spectral transmission from these...
Well-aligned ZnO/Ga<sub>2</sub>O<sub>3</sub> core/shell nanowire arrays were fabricated by VPT and the sputtering method as self-driven solar-blind photodetectors.
Abstract Core–shell nanostructures can combine the advantages of different functional materials to realize property tunability and enhance optical optoelectrical performance. Here, vertically aligned ZnO/AlN core/shell nanowires have been facilely fabricated by sputtering AlN layer onto ZnO grown vapor phase transport. The morphological structural characterization reveals that single‐crystal shell with thickness ≈15 nm is coated uniformly on nanowire diameters ≈330 nm. exhibits 24 times...
Plasmonic hot carriers have the advantage of focusing, amplifying, and manipulating optical signals via electron oscillations which offers a feasible pathway to influence catalytic reactions. However, contribution nonmetallic thermal effects on overall reactions are still unclear, developing methods enhance efficiency catalysis is critical. Herein, we proposed new strategy for flexibly modulating electrons using plasmonic heterostructure (named W18O49-nanowires/reduced-graphene-oxides)...
We observed the dramatic enhancement of intrinsic spontaneous and stimulated emission as well ensuing suppression defect-related green in Au-decorated ZnO microrods. A series spectral experiments theoretical analysis demonstrated an electron transfer assisted process by surface plasmon (SP) resonant coupling between Au nanoparticles ZnO. The mechanism indicates approach to enhance UV through extra excitation visible light similar that for defect Based on mechanism, externally enhanced...

Respiration rate and volume are important physiological indicators of human health. They can indicate cardiovascular health status cardiopulmonary function. Here, we demonstrate a compact breath monitoring system based on wearable tilted fiber Bragg grating (TFBG) curvature sensor for respiration monitoring. With the assistance custom designed breathing tube, TFBGs provide very reproducible highly sensitive, real time response to changes during respiration. The miniaturized cost effective...

Photoelectrochemical behavior of Au NPs–ZnO nanorod array for glutathione detection.
Tilted fiber Bragg grating (TFBG) sensors are widely used in biochemical and electrochemical sensing due to their high sensitivity refractive index (RI) of the surrounding medium. Ability TFBGs measure small RI change is currently limited discrete spectral characteristics TFBG cladding modes. Here we propose a method both large changes with accuracy by measuring derivative intensity entire mode envelope. The peak curve provides continuous linear response change, which overcomes problem...
Constructing heterostructured nanomaterials with integrating different functional materials into well-oriented nanoarchitectures is an efficacious tactic to obtain high-performance photocatalysts. In this paper, we fabricated three-dimensional ZnO–WS2@CdS core–shell nanorod arrays as visible-light-driven photocatalysts for efficient photocatalytic H2 production. This unique heterostructure extends visible-light absorption and provides more active sites. More importantly, the build a...
In this report, we mainly investigate the optical property differences between CsPbBr 3 @SiO 2 quantum dots (QDs) and QDs. The photoluminescence demonstrates that QDs have similar exciton binding energy. Both present bandgaps (PL) linewidth broadening as temperature increases from 10 K to room temperature, which is attributed thermal expansion electron-phonon coupling. fitting results show bandgap coefficient, but weaker interaction. Temperature-dependent time-resolved (TRPL) PL lifetime...
