By virtue of their high uniformity and stability, metal oxide-based surface-enhanced Raman spectroscopy (SERS) substrates have attracted enormous attention for molecular trace detection. However, strategies further enhancing the SERS sensitivity are still desired. Herein, MoOx/WOx nano-heterojunctions constructed by mixing MoOx WOx together (MoOx/WOx hybrid) with diverse weight ratios. Using a 532 nm laser as excitation source R6G reporter, it is shown that signal intensity (for peak @ 1360...
Abstract Vacuum electronic devices offer superior electron mobility and spatiotemporal manipulating precision, with recent challenges focusing on ultrafast pulses for high‐frequency, high‐energy, high‐resolution applications. Plasmon‐mediated emission (PMEE) nanocathodes provide a promising solution by producing high‐quality while simplifying the beam manipulation. In this study, we developed PMEE Au‐on‐Gr nanocathode using vertically aligned few‐layer graphene decorated gold nanoparticles,...
Abstract Ultrashort pulsed electron beam with high brightness and low energy spread enables ultrahigh resolution of spatio-temporal characterization materials devices. So far, this is done using ultrashort pulse as probe laser pump. Adding powerful analytical capability multimode-excitation urged to meet rapidly rising need. We envision that it will provide plentiful new insides if characterizations are carried out excitation simultaneously pulses electromagnetic wave pulses. In particular,...
